Polynomial:- (poly meaning "many") consisting of several terms 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). Academic Vocabulary Box Method
