How to Factor Algebraic Equations:
<span>In mathematics, factoring is the act of finding the numbers or
expressions that multiply together to make a given number or equation.
Factoring is a useful skill to learn for the purpose of solving basic
algebra problems; the ability to competently factor becomes almost
essential when dealing with quadratic equations and other forms of
polynomials. Factoring can be used to simplify algebraic expressions to
make solving simpler. Factoring can even give you the ability to
eliminate certain possible answers much more quickly than you would be
able to by solving manually.
