OBJECTIVE

I can show multiplying polynomials with the BOX METHOD.

MULTIPLYING POLYNOMIALS

Binomial X Binomial

(x + 2)(x + 4)

BOX Method

STEP 1: Draw the BOX

BOX Method

2x2 for a Binomial x Binomial

BOX Method

STEP 2: Place terms on outside

BOX Method

STEP 3: Multiply

Find the area of each box.
