Lesson Summary:

In this lesson, we learn how to write a polynomial function using four given zeros. We start by writing the zeros as linear factors and then simplify the expression using the difference of two squares. We then perform multiplication and rearrange the terms to write the polynomial function in descending order. By finding the zeros of this polynomial function, we can determine the points where the graph intersects the x-axis.

Lesson Description:

Using four zeros to find a polynomial function

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.
