Chapter 10 - Section 10.3 - Finding Binomial Factors - Exercise: 30

Answer

$(b+6)(b-5)$

Work Step by Step

$b^2+b-30$ has no common monomial factors $=(\ \ \ \ \ \ \ \ )(\ \ \ \ \ \ \ \ )$ $=(b\ \ \ \ \ \ )(b\ \ \ \ \ \ )$ $=(b+\ )(b-\ )$ The factors of -30 must have unlike signs. $=(b+6)(b-5)$ 6 and -5 have a sum of 1 and a product of -30.
