Chapter 10 - Section 10.3 - Finding Binomial Factors - Exercise: 24

Answer

$(b-6)(b-9)$

Work Step by Step

The first term in each binomial must be b, since $b^2$ has no coefficient. The operation in each binomial must be subtraction, since the trinomial has a positive and a negative term. $-6+(-9)=-15$ and $-6\times(-9)=54$, so the other two terms are -6 and -9.
