Using Descartes rule of signs to find possible zeros

The video tutorial explains how to find the zeros of a polynomial, focusing on real and complex zeros. It covers the process of identifying positive zeros by counting sign changes in the polynomial function and discusses the handling of zero terms. The tutorial also explains the subtraction of even numbers from the count of sign changes to determine the number of positive zeros. Additionally, it addresses the calculation of negative zeros and complex solutions, emphasizing the importance of understanding the degree of the polynomial to find the total number of solutions.
