Lesson Summary:

In this lesson, we learn how to find all the values of x that make our function equals 0. By factoring the function into a set of linear factors, we can separate the equation and find the roots. The roots are the values of x that make the function equal to 0. In this case, the roots are x equals 0, 1, and negative 1.

Lesson Description:

Find the values of x when f(x) = 0

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.
