Lesson Summary:

In this lesson, the teacher explains how to complete the square to solve for a function's values. The first step is to make sure there is no coefficient in front of the x squared. Then, the b over 2 squared value is determined, which is added and subtracted from the equation to create a perfect square. This perfect square can then be factored out and used to find the zeros or the standard form of the function.

Lesson Description:

Showing how to complete the square

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.
