How can you multiply two polynomials? A look at area models and distributive property . . . aka (FOIL) (x + 8 )(x + 3) erase Our like-terms are always going to be diagonal of each other! Knowing this can help us prevent multiplication mistakes. combine your like-terms This will happen every single time!

Write the product of two binomials modeled by each rectangular array of algebra tiles. In parts (c) and (d), first draw the rectangular array of algebra tiles that models each product. a. (x + 3)(x − 2) = b. (2x − 1)(2x + 1) = c. (x + 2)(2x − 1) = d.
