Synthetic Division
At about the 0:34 mark, the teacher says the zeros of these would be 5 and 4; he should have said 5 and -4.
Determining factors and listing the zeros of a polynomial using synthetic division
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.
- If I am given a linear factor of a polynomial, then how can I check to make sure that it is actually a factor using synthetic division?

Staff Review
If you are given a polynomial and a linear factor of the polynomial, then you can use synthetic division to verify that the given linear factor is indeed a factor. This lesson shows how you can do that, and it goes on to discuss how to find the zeros of the polynomial.
