Factoring Binomials - Difference of Squares
Objective: I can factor binomials that are difference of squares.
A difference of squares is a binomial of the form:
a2 – b2
Take note that the first term and the last term are both perfect squares.
When we factor a difference of two squares, we will get
a2 – b2 = (a + b)(a – b)
This is because (a + b)(a – b) = a2– ab + ab – b2 = a2– b2
Read the lesson on Difference of Squares if you need more information.
