Answer:

Step-by-step explanation:

To evaluate the expression (ab^2-bc^2)(a^2c-abc), we first substitute the given values of a, b, and c:

(ab^2-bc^2)(a^2c-abc)

Substituting the values:

((2*-2)^2-(-2)(-1/2)^2)(2^2*-1/2-2*-1/2)

Simplifying:

(4*4-(4)(9/16))(4*-1/2-4*-1/2)

Simplifying further:

(16-36)(-3/2-3/2)

Simplifying again:

(-20)(-3)=60

So, our final answer is 60 when a=2, b=-2, c=-½ .
