step-by-step explanation:

B) -5, 5, -7, 7

Step-by-step explanation:

3x² - bx + 2

factor:

(3x - 2 )(x - 1) = 3x² - (5)x + 2 so 5 does work

(3x - 1 )(x - 2) = 3x² - (7)x + 2 so 7 does work

(3x + 2 )(x + 1) = 3x² + 5x +2 = 3x² - (-5)x + 2 so -5 does work

(3x + 1 )(x + 2) = 3x² + 7x + 2 = 3x² - (-7)x + 2 so -7 does work
