### Meets NCTM Standards:

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.
Completing the square of two functions
• How do I complete the square?
• How do I find the zeros of a quadratic function?
• How do I complete the square for the function f(x)=x^2+6x+8?
• How do I complete the square for the function f(x)=-x^2+2x+5?
• What are the zeros of the function f(x)=x^2+6x+8?
This lesson gives two examples of completing the square. On one of the functions, the teacher goes on to show how to find the zeros of the function once you have completed the square.
