How to apply multiplication to write polynomial in standard form and find degree

The video tutorial explains how to transform a multiplication expression into a sum of monomials. It begins by identifying the need to apply operations to rewrite the expression. The teacher demonstrates distributing terms and combining like terms to simplify the expression. The final expression is presented in descending order, and its properties, such as degree and leading coefficient, are discussed.

What is the degree and leading coefficient of the polynomial discussed?
