Best ResponseYou've already chosen the best response.0You need to factorize the polynomial. Your answer of (z+6)(z3) was almost right but your positives and negatives are wrong. If you expand it you get z^2 + 3z  18 but its z^2  3z  18 in the question. When you factorize its the numbers which multiply to the last number and add to the coefficient of the middle term (with z). Therefore the answer is (z6)(z+3) this is because 6+3 = 3 6*3=18
