Multiplying and Combining Algebraic Expressions

This video tutorial teaches how to multiply binomials using an area model. It begins by introducing the concept of binomials and polynomials, followed by setting up an area model. The tutorial then demonstrates the multiplication of terms within the model, explaining the addition of exponents and handling of negative numbers. Finally, it covers combining like terms to simplify the expression, resulting in the final product of the binomials.
