Answer:

the simplified expression is -12x^3+28x^2

B is the correct option.

Step-by-step explanation:

We have been given the expression -4x^2(3x-7)

Using the distributive property a(b+c)=ab+ac and simplify

-4x^2(3x-7)\\\\=-4x^2\cdot3x+(-4x^2\cdot(-7))\\\\=-12x^3+28x^2

Therefore, the simplified expression is -12x^3+28x^2

B is the correct option.
