### Factoring the Difference of Two Squares

The special rule for factoring the difference of two squares is a

^{2}– b^{2}= (a + b)(a – b).Sometimes, this rule needs to be applied more than once to completely factor the original polynomial.

Some polynomials require several methods to be factored completely. Always start by finding the Greatest Common Factor. Then try other methods.

You can solve some quadratic equations by factoring the trinomial and then using the zero product property.
