This lesson demonstrates how to factor binomials that are the difference of two squares.

Tutorial

In this lesson, I'll show you how to take scary looking binomials like 9x^4-81x^8, and rewrite them as the difference of two squares, e.g. a^2 - b^2 -- simple and elegant. The point of that is that it becomes very easy to factor -- which I'll show you, too.
