Question

Simplify the expression

Answer 1

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 2

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.
