How to find the number of real and complex zeros using descartes rule of signs

The video tutorial explains how to determine the possible zeros of a polynomial using the rational zero test and Descartes' Rule of Signs. It covers the distinction between rational and irrational zeros, the process of finding negative real zeros, and the concept of symmetry in polynomials. The tutorial also discusses the fundamental theorem of algebra and explores different scenarios for the number of real and complex zeros.
