Expanding Binomials: A Volume Model Proof

The video tutorial explains how to expand the cube of a binomial expression (A+B)^3 using a volume model. It addresses common misconceptions about distributing exponents and demonstrates the correct expansion through a visual model. The lesson includes an example with (X+5)^3, showing how to calculate the volume of each section of the cube and combine like terms to achieve the expanded form. The tutorial concludes by summarizing the key points and reinforcing the correct method for binomial expansion.
