Amsco Integrated Algebra I: Factoring the Difference of Two Perfect Squares
 This is a free lesson from our course in Amsco's Integrated Algebra

 This lesson explains how to factorize difference of two prefect squares. A perfect square is the result of multiplying a number by itself. An expression of the form a2-b2 is called difference of two perfect squares. Factorizing the difference of two perfect squares is the reverse of multiplying the sum of two terms by the difference of the same two terms. For example, 25m2-n2 = (5m)2-(n)2 = (5m+n)(5m-n). The video below will explain in detail with the help of several examples.
