Learn how to use Descartes rule of signs and the fundamental theorem of algebra

The video tutorial covers the process of finding polynomial zeros, including rational, irrational, and complex zeros. It introduces Descartes' Rule of Signs as a method to determine the number of real positive, real negative, and complex zeros without extensive calculations. The tutorial demonstrates the application of this rule and evaluates the function for negative zeros, concluding with a summary of the findings.
