Factoring Polynomials - An Ultimate Approach

!±8± Factoring Polynomials - An Ultimate Approach

Factoring polynomials is a "must know" to understand algebra and score excellent grades in algebra. In this presentation we will explore the ultimate approach to factoring polynomials. Starting from factoring a monomial we will discuss every aspect of factoring polynomials.

To factor any kind of polynomial, knowledge of greatest common factor (GCF) is mandatory. If the students don't have the basic understanding of factoring numbers, they should review prime factorization of numbers first.

There are the following steps for factoring polynomials:

1. Find if there is any greatest common factor in the terms of given polynomial:

If the polynomial has the GCF, pull it out from each term of the polynomial by using the brackets. For example;

3a² + 6ab - 9a has "3a" as the GCF. Pull "3a" out as shown below to factor the polynomial;

3a (a + 2b - 3)

2. If the polynomial is a binomial (having two terms only), find if it is the difference of squares. Some times, by taking the GCF away, the binomial becomes the difference of squares. There is a special method for factoring difference of squares and I will discuss that in detail in my coming articles.

3. If the polynomial is a trinomial, again try to pull the greatest common factor away if you can. There is a special way to factor a trinomials and I am going to explain this topic alone in a separate article.

4. If the polynomial has four terms, then try to rearrange the terms and separate them into pairs of two's having greatest common factors. Take the greatest common factor out from each pair and see if you get two same brackets. For example; consider we have a polynomial, 4u² + 3a + 2u + 6au and we want to factor it.

There are four terms in the polynomial and there is no greatest common factor other than one. If we rearrange the terms and try to find the greatest common factor in the pairs of two terms, it might be possible to factor the polynomial that way.

So rewrite the polynomial by rearranging the terms as shown below:

4u² + 2u+ 3a + 6au

Look at the first pair "4u² + 2u" it has "2u" its GCF, pull it out as "2u (2u + 1)". Similarly factor the second pair as "3a (1+2u)". But, (1 + 2u) is same as (2u + 1), hence we can interchange them for simplicity.

= 2u (2u + 1) + 3a (2u+1)

Now, (2u + 1) is the common factor and pull it out as shown below:

= (2u + 1) (2u + 3a)

All the steps can be written together as follows;

4u² + 3a + 2u + 6au

= 4u² + 2u + 3a + 6au

= 2u (2u + 1) + 3a (2u+1)

= (2u + 1) (2u + 3a)

You can FOIL it to check your answer, if you get back the original polynomial.

Getting to Know Vedic Arithmetic a Little Bit More

!±8± Getting to Know Vedic Arithmetic a Little Bit More

It is a common sentiment among humans, with a wee bit of emphasis on kids, that mathematics at its lowest and most raw form is simply hard. There are, however, different aspects of mathematics that we have to learn about more for they can be useful in developing strategies in dealing with real life situations. Vedic arithmetic is one of these less known mathematical concepts.

Basically, vedic arithmetic is a subset of vedic mathematics. This concept involves an algorithm operation which focuses on the algorithmic and correctness issues concerning numerals. There are questions concerning the label for this concept as critics continue to demand evidence supporting the concept's right to be referred to as vedic as well as mathematics. The lack of evidence is specific on the aspect concerning the connection of the whole system with that of the verdict sutras.

In its simplest form, verdict arithmetic involves numbers and numbers along with the other different basic concepts in mathematics such as the four major operations, square and square root, cubes, fractions and decimals. With the use of the equations, we can easily get to the answers to any numerical problems. Men of science usually make use of such equations to provide scientific calculations involving theories and methodologies in physical sciences. The use of the vedic formulas are helpful in making the calculation as fast as lightning and in order to end up with one liners for the answers.

The history of vedic arithmetic dates back a long time ago. Sri Bharati Krsna Tirthaji gave this name to refer to this mathematical concept as this is described as a form of ancient system rediscovered from the Vedas. There was a time when this concept was used to make sense of the way the mind works. It was a great help in getting the students directed towards the most appropriate way of solving the equation.

In our modern age of computers and calculators, a lot of people have shied away from developing skills of mental math, in particular, the basic methods of mental arithmetic. School children have asked why there is a need to learn about it when a calculator is readily available. This is a valid reason and can really catch the teacher off guard. This is however, a challenge left on the hands of our educators.

The dangers of trillions of dollars of debt

!±8± The dangers of trillions of dollars of debt

We are not out of the woods yet. The stock market has begun to take measures for the experimental aspect of the end of the bear market, Chrysler and General Motors are steps on the road to a more streamlined and, hopefully, more prosperous and credit markets begin to take steps to attempt a opening up of the credit.

But while this is good news, apparently, the problem is that the TARP, TRAP, GM, Chrysler, the reform of social security and the warthe rest of the federal budget is necessary, the costs out of control.

The federal government has a deficit of 1,700 billion U.S. dollars this year because of spending more than income.

Our national debt is now estimated at about $ 11 billion.

Most people have no idea of ​​the difference between a trillion and a trillion dollars. All most people know is that it sounds like a lot of money, but nothing that can not be addressed.

When Istarted college, we worked some problems with "scientific notation", which show a way to enter numbers, if it is too big for a pocket calculator. Sun $ 1.7 trillion is $ 1,700,000,000,000 or 1.7 x 1012th That is, a point seven times ten to the twelfth power.

To understand a bit 'better, try this for a million dollars is to return would pay a dollar a second for the next 12 days.

For the return of a billion dollars, you take a second to the U.S. dollar for the next 31Years.

A trillion dollars for one U.S. dollar, it takes a second for the next 31 thousand years.

The government needs the growth of debt and the deficit over the next three years for the control or we are all responsible for the collapse of our system as we know it now. This means that forcing by a ghost, our elected politicians to take responsibility for their actions to be taken to get into questions.

They are thinking that there are too many lawyers in Congress and not enoughAccountants, we need more people who understand the calculation of budgets and fewer people who write the offer for lack of legislation for special interests to the left or right.

We're Americans. All of us, whether we look at each point or less. We are citizens of the United States of America. Now it's time for us to return, to maintain the principles that underpin the country and start our representatives accountable for their actions do, andfind solutions to these problems, rather than up or placing the sidewalk cracks.

Chemistry can be a very exciting. You can mix substances, new things, change the color of the products, create odors and go BANG! The chemistry is the backbone of pharmaceutical research, detective work and the development of the CIS food. So the chemistry very attractive for many students to recognize them, must have some math skills.

But do not panic, your math skills, the basic chemistry needed, very simple and can be mastered by one. So here's a list ofthe most commonly used math skills in chemistry.

Scientific notation

Scientific notation is a very useful tool. It allows chemists to write very large and very small numbers easier. It involves the use of orders of magnitude the number of digits that you need to write, is lower.

10, 000 1 x 10 ^ 4
1 is 0.0001 x 10 ^ -4

Significant figures (figs SIG)

Significant figures (sig figs) help the chemical integrity of your data. The calculations are only as good as theThe collected data. The data is only as good as the tools used and the tool is only as good as the person using it. If the instrument measures only one-tenth of a unit, can not be your best accuracy of the instrument. Understand how important people work preserves data integrity.

Fractions

Many calculations in chemistry require the ability to manipulate, fractions. You need to understand how to reduce fractions and common fractions significantlyDenominator.

Decimals

The ability to work with decimals is very important, because most chemical measurements are not exact. Many of your measures will be part of things (fractions) and it is best to use the numbers as decimal fractions in the description of the data. You need to have values ​​you know and how to convert fractions to decimals.

Percentages

It 'important to understand percentages in chemistry, because often, the data will be converted to a percentage ofComparisons. Percentages are not very difficult to understand. The percentages are just another way of writing fractions and decimals. Example: 1 / 2 =. 50 = 50%

Pre-Algebra

Most problems require only simple chemical pre-algebra skills. If you can solve simple equations and basic scheme of a coordinate system, then your algebra skills are sufficient. No need to pre-calculus or calculus.

Computer

For the chemistry even easier, you should invest in a TI-84Graphing calculator. The time and headaches, which are resolved by learning to use a computer is well worth the investment. A TI-84 not only the usual arithmetic, but it may help to sort and graph the data.

Here are some basics to understand aboutCasio fx-260:
Find out the location of the keys. Check out the features that lead to the keys. Use the 'On' to reset the computer or clear the memory. How to use the 'Clear' and 'All Clear' buttons or functions, to insert the last number or to erase the memory. Use the number keys 0-9 and function keys for basic addition, multiplication, subtraction and division. Learning the position of the decimal and percentage is, how and when each is used. With the "Shift"- In other buttons to modify other functions. As the "change sign" and "Hamlet" buttons, and if I use them. As the 'Square "and" Square Root "key, and if you use them. The "clip" Buttons are important because these keys are used to control the order of mathematical operations. Understanding the keys to increasing the numbers of all other powers, and the exponents - used in scientific notation - key 'EXP'.

Sounds complicated? Sure, and the Casio pocket calculator usesGED test has additional features that can be used for complex mathematical functions.

But do not worry. While it seems a lot to learn - and understand - the test requires only a basic knowledge and application of some functions. And this knowledge to help those who support the test really loosen the test is more complicated problems.

The Casio fx-260 is well worth learning. Understanding goes a long way toward reducing "math anxiety" and should improve the final GEDmathematics score.
