If a = 2, b = -2 and c = -12 1 2 , evaluate (ab2 - bc2)(a2c - abc)

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

Answer Details

(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
