Lesson Description:

Find all the zeros of a polynomial to the fourth degree

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:
  • How do I find all the possible rational roots of a fourth degree function?
  • How can I find out how many positive real roots and negative real roots a polynomial might have?
  • How many roots can a fourth degree equation have?
  • How can I use synthetic division to help factor a polynomial?
