Determine all of the possible positive, negative and complex zeros of a polynomial

The video tutorial explains how to determine the number of positive and negative real zeros in a polynomial by analyzing sign variations. It covers evaluating expressions with negative X, simplifying expressions, and understanding the implications of sign changes. The tutorial also reviews the rules for counting zeros based on variations and the degree of the polynomial, concluding with a discussion on complex zeros.

Discuss the rule regarding the number of variations and how it relates to the possible zeros of a polynomial.
