Polynomial Multiplication Special Rules

Of course when faced with multiplying two polynomials (binomials) you can just use the F.O.I.L. method and call it a day.  However recognizing that you are multiplying binomials with the following pattern

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

can allow you to break out a secret weapon to get the product.  So what is this great tool to help you find the product?  It’s special polynomial rules (below).  However the more important benefit to mastering these rules is when you have to factor polynomials-  believe me you will need to know these rules to factor!

 

some key topics that involve polynomial special multiplication rules:

* polynomial factoring
* radical equations
* working with more complex variable expressions in higher level math to include pre-calculus and beyond
