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 .
