Lesson Summary:

In this lesson, you'll learn how to find a polynomial using zeros. The zeros are the x-intercepts, where the graph crosses the x-axis, and these can be written as a set of linear factors. By FOILing these factors, you can expand and simplify, and then distribute the x to every term to find the polynomial function.

Lesson Description:

Using the Zeros to find 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.

Questions answered by this video:
  • If the zeros of a function are 0,2,5 give the coordinates of the x-intercepts.
