Lesson Summary:

This lesson teaches how to solve equations using the square root method. The first step is to isolate the square root by performing inverse operations. Once the square root is isolated, the inverse operation of the square root (squaring) can be used to solve for the variable. The final solution will typically have two answers, one positive and one negative.

Lesson Description:

Solving an equation by the square root method

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.
