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.
