Learn to find the possible real positive & negative zeros from descartes rule of signs

The video tutorial explains how to find rational zeros of a polynomial using Descartes' Rule of Signs. It covers the process of determining the number of possible real positive and negative zeros by analyzing sign changes in the polynomial's terms. The tutorial also discusses the implications of subtracting even numbers from the count of sign changes to determine the possible number of zeros.
