Lesson: Expanding an Expression to a Difference of Two Squares Mathematics

In this lesson, we will learn how to multiply the sum of two terms by their difference to get the polynomial known as the difference of two squares.

Lesson Plan

Students will be able to

recall and apply the formula of the difference of two squares to expand a product of a sum and a difference,
understand geometrically why a difference of two squares is the product of a sum and difference,
find the value of an unknown using the formula of the difference of two squares.
