Concept Development
Polynomial:- (poly meaning "many") consisting of several terms
separated by addition and subtraction.
Step 1: Write one of the polynomial on the top and the other on the side of a box.
*It does not matter which goes where.
Step 2: Multiply the edges (adding exponents) and together and fill in the corresponding spot.
Step 3: Add the diagonal products (like terms).
