When recognizing that you are multiplying binomials with the following pattern

(a + b)(a – b), (a + b)(a + b), (a – b)(a – b)

you can break out a special multiplication rule to get the product. However the more important benefit to mastering these rules is when you use them in reverse to factor polynomials- knowing these patterns will be critical as you factor polynomials.

Key concepts to remember:

* factoring skills are critical in algebra

* knowing these special factoring rules will also make polynomial multiplication easier
