Apply Descartes rule of signs to a polynomial to find the roots

The video tutorial explains Descartes' Rule of Signs, focusing on determining the number of positive, negative, and complex solutions for a polynomial equation. It covers how to identify sign changes to find real zeros and uses F(-X) to calculate negative solutions. The tutorial also discusses creating a chart to visualize possible solutions and emphasizes the importance of understanding the degree of the polynomial.

What does the 'cartel of sign' refer to in the context of finding real zeros?

What is the relationship between the degree of a polynomial and the total number of solutions?

How do you determine the number of complex solutions based on positive and negative real zeros?
