Description

7 steps: (1) Monomial × polynomial: 3x(2x²-5x+1) = 6x³-15x²+3x. Distribute to each term. (2) Binomial × binomial: use FOIL (First, Outer, Inner, Last). (3) (x+3)(x+2): F=x², O=2x, I=3x, L=6. Sum: x²+5x+6. (4) This IS the area model algebraically! (5) Trinomial × binomial: distribute each term. (6) (
