Lesson Summary:

In this lesson, students learn how to use the quadratic formula to find zeros of a polynomial. The formula involves plugging in the values of A, B, and C from the polynomial equation and working out the equation to find the values of x. The video demonstrates how to use the formula with an example, as well as when it is appropriate to use quadratiform versus complete square methods.

Using the quadratic formula to find the zeros of a polynomial

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.
