Free Algebra

Getting free algebra help might not always be easy. Usually, friends and family will help out if possible but if they are not available or can’t do the homework problem, then other places have to be found. Many websites and places on the Internet offer free homework help online by providing math worksheets, formulas, practice tests and quizzes. One of the commonly used methods of getting help consists of posting an algebra problem on a blog, forum or message board. One of the problems of doing it this way is that the person who posted the homework problem may have to wait a long time before anyone answers. Another problem using this method is that the response may be inadequate. An example would be where an answer is posted but the means of obtaining the answer isn’t. Sometimes, an answer by itself is insufficient. What is really needed is the method of solving the math problem with an explanation of how it works. If the website provides feedback, however, then it might be possible to get a complete answer.

Sometimes, only a specific algebra topic needs to be explained. One area of algebra that many students seem to need help with homework is factoring. Unlike some other methods in algebra, factoring requires many steps. There is no simple math formula or equation that does factoring except for the quadratic formula and certain cubic functions. For example, there are special factoring formulas for certain polynomial configurations such as the perfect square, differences of squares and cubics.

The simplest factoring method for quadratic equations is grouping terms together in the polynomial and factoring out the common factors. This method can be fast but it doesn’t work for every polynomial. Another factoring method that works well is the trial method. This involves setting up the parenthesis and factoring the leading coefficient along with the constant. This method can be slow when there are coefficients with many factors. Also, it does not work for many polynomials. When there are a great number of factors then it is better to use a table to write down the factoring process. One column of the table can be for pairs of factors and another column can be for their sum. If the pairs of factors add up to the middle coefficient in the quadratic equation, then the right pair of factors have been found. Just like the previous factoring procedures, however, this method does not work for every polynomial.

There are two factoring methods that work for every quadratic equation. The first is called complete the square. The second one is based on completing the square for the standard or general form of a quadratic polynomial and results in a math formula called the quadratic formula. The first method, complete the square, involves adding a value to the quadratic equation on both sides to determine a perfect square trinomial on one side of the equation and a constant on the other side of the equation. Then the result is placed in factored form with the square root taken on both sides. With the quadratic formula, complete the square is already done and the only thing that remains to be done is to plug in the values of the constants and coefficients into the formula. These two procedures are used frequently in math because they can solve any quadratic equation. They can result in real or complex answers, however.

In addition to factoring, other important algebra skills include expanding a polynomial or quadratic equation in factored form. This is generally done through distribution. The Law of Distribution is an important rule that is used in all of math including algebra. A special form of distribution for quadratic expressions is called FOIL which means: First, Inside, Outside and Last.

Graphing linear equations is also required in algebra. A linear equation is a formula for a straight line. The linear equation includes the slope of the line as well as its intercept.

While many websites provide information in one form or another, the goal should be to understand algebra. This is accomplished by understanding the rules, definitions and formulas that are used. When searching for free algebra help, a website should be able to help in understanding as well as providing free homework answers or solutions.
