Strategy 2: Grid Multiplication without Algebra Tiles

The procedure for using grid multiplication without algebra tiles to multiply binomials is similar to the procedure used with algebra tiles. Use symbols to write one binomial vertically and the other horizontally. Multiply each pair of monomials; then, find the sum of the products by combining like terms to determine the final product.

Example 2

Multiply using grid multiplication without algebra tiles.

Write one binomial vertically and the other horizontally.

Multiply each pair of monomials.

Now compute the rest of the products.


Add the terms inside the grid, simplifying where possible.

Write a final statement.
