About This Lesson
http://www.freemathvideos.com In this video series I show you how to find the zeros of a polynomial. We will explore using the Rational Zero and Descartes rule of signs to help us narrow down our zeros. We then use synthetic division, factoring, completing the square and the quadratic formula to find the exact zeros we are looking for. The zeros of a polynomial are very important in helping us find where the graph crosses the x-axis.
