Answer:

B

Step-by-step explanation:

given

- 4x²(3x - 7)

multiply each term in the parenthesis by - 4x²

= (-4x² × 3x) + ( - 4x² × - 7)

= - 12x³ + 28x² → B



Answer:

the simplified expression is [tex]-12x^3+28x^2[/tex]

B is the correct option.

Step-by-step explanation:

We have been given the expression [tex]-4x^2(3x-7)[/tex]

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

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

Therefore, the simplified expression is [tex]-12x^3+28x^2[/tex]

B is the correct option.
