Box Method for Multiplying Expressions

This video tutorial explains how to multiply binomials using the box method, a common Algebra 2 technique. It begins with an introduction to binomials and the box method, followed by three examples: multiplying x + 3 and x + 4, x + 1 and x + 5, and 3x + 2 and x - 3. Each example is demonstrated step-by-step, highlighting the process of filling the box and combining like terms. The video concludes with a set of practice problems for viewers to solve independently.
