If a = 2, b = -2 and c = -\(\frac{1}{2}\), evaluate (ab2 - bc2)(a2c

If a = 2, b = -2 and c = -\(\frac{1}{2}\), evaluate (ab² - bc²)(a²c - abc)

-28

-30

-34

Correct answer is D

(ab² - bc²)(a²c - abc)

[2(2)² - (- 2x\(\frac{1}{2}\))] [2²(-\(\frac{1}{2}\)) - 2(-2)(-\(\frac{1}{2}\))]

[8 = \(\frac{1}{2}\)][-2 - 2] = \(\frac{17}{2}\) x 4²

= -34
