In this lesson, you will learn how to solve an equation by completing the square. The first step is to ensure that the equation is in the form of x squared plus bx. Next, you find b over 2 squared and add it to both sides. Then, rewrite the equation as a perfect square and simplify it. Finally, solve for x by taking the square root of both sides and subtracting to get x equals a plus or minus the square root of b.

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.
