Polynomial Multiplication and Simplification

The video tutorial explains how to use the box method for multiplying polynomials. It begins with an introduction to the method, likening it to a multiplication table or Punnett square. The tutorial then demonstrates setting up the box for a binomial times a trinomial, followed by detailed steps for multiplying terms inside the box and combining like terms. An example of multiplying a trinomial by a binomial is provided to reinforce the concept.
