Question

Factor completely, then place the factors in the proper location on the grid.

b2 - 7b + 12

Answer 1

(b - 4)(b - 3)

Explanation:

b² - 7b + 12

consider the factors of the constant term (+ 12) which sum to give the coefficient of the b- term (- 7)

the factors are - 4 and - 3 , since

- 4 × - 3 = + 12 and - 4 - 3 = - 7 , then

b² - 7b + 12 = (b - 4)(b - 3)
