Lesson 2
Factoring:
Difference of Two Squares
What’s In
We have learned in lesson 1 about factoring and common monomial factor. There are different types of factoring polynomials. Next to common monomial factor is factoring difference of two squares. This type of factoring needs mastery of squares and square roots.
