Determining if a equation is a polynomial or not

The video tutorial explains how to classify polynomials and determine their degree and leading coefficient. It outlines the rules for classifying polynomials, such as not having variables in the denominator or multiplying different variables in the same term. An example is provided where a term with X^3 * Y is shown not to be a polynomial, as it violates these rules. Consequently, the degree and leading coefficient cannot be determined for such terms.
