Understanding Binomial Multiplication Using a Table

The video tutorial explains how to multiply two binomials using a table method. It begins by setting up a 2x2 table, placing one binomial on the top and the other on the side. The tutorial walks through the process of multiplying each term in the rows by each term in the columns, combining like terms, and simplifying the expression. Two examples are provided to illustrate the method, showing how to handle different binomials and simplify the results. The video concludes by emphasizing the equivalence of different forms of the final expression.

What is the first step in setting up a table for multiplying two binomials?

• Write both polynomials on the left column.

• Write both polynomials on the top row.

• Write the first polynomial on top and the second on the side.

• Write the second polynomial on top and the first on the side.
