Hank’s teacher asked him to verify that the product (y−3)(y2 3y 9) is a difference of cubes. He used the distributive property to multiply the binomial times the trinomial. Before simplifying, his product was a polynomial of the form y3 3y2 ay−3y2−ay−27. What is the value of a in the polynomial? 3 9 18 27.
