Master Determining the number of real positive, real negative and complex zeros, descartes rule of s

The video tutorial explains how to determine the number of positive, negative, real, and complex roots of a polynomial using Descartes' Rule of Signs. It covers the process of identifying sign changes in polynomial terms to find positive and negative real roots. The tutorial also provides examples to illustrate the method and discusses how to calculate complex solutions when real solutions are known.
