Finding All of the Zeros of a Polynomial Including Complex

The video tutorial covers the process of identifying factors of a polynomial, using the remainder and factor theorems to check for zeros, and exploring the factorization of cubic polynomials. It also discusses the quadratic formula for finding complex solutions and explains Descartes' rule of signs to determine the number of positive and negative real zeros in a polynomial.
