Multiply a Trinomial by a Trinomial Using a Rectangle - Math Tutorial

The video tutorial explains how to multiply trinomials using a rectangle model. It begins by introducing the concept and setting up the model by breaking down the trinomials into sections. The tutorial then demonstrates how to calculate the area of each section and combine like terms to simplify the resulting polynomial. The approach helps organize the multiplication process and reduce errors.
