Factoring and Perfect Squares Practice

The video tutorial explains how to factor expressions using the difference of squares method. It begins with an introduction to the concept, followed by a detailed walkthrough of a sample problem involving the expression 9x^2 - 4/25. The instructor demonstrates how to rewrite the terms as perfect squares and apply the product of their sum and difference to factor the expression. The video concludes with a call to action for students to practice similar problems and hints at combining this method with common factoring in future lessons.
