In this lesson, the instructor teaches how to factor a quadratic equation using a perfect square. The first step is to check if anything can be factored out. Then, the instructor advises to look for special factors like difference of two squares or perfect squares. The example problem is a perfect square, which allows the instructor to rewrite it as (X + 9) squared, making it easier to solve. The lesson emphasizes the importance of looking for shortcuts and special factors to make factoring easier.

I show how to solve math problems online during live instruction in class. This is my way of providing free tutoring for the students in my class and for students anywhere in the world. Every video is a short clip that shows exactly how to solve math problems step by step. The problems are done in real time and in front of a regular classroom. These videos are intended to help you learn how to solve math problems, review how to solve a math problems, study for a test, or finish your homework. I post all of my videos on YouTube, but if you are looking for other ways to interact with me and my videos you can follow me on the following pages through My Blog, Twitter, or Facebook.
