Distribute what is outside the parenthesis first (-&2) to get

-4x^3-x^2+2x^3-6x^2

Then combine like terms to get

-2x^3-7x^2

So your answer is D.


Hope this helped :)

Answer:

-2x³ - 7x².

Step-by-step explanation:

- (4x³ + x²) + 2(x³ - 3x²)

= - 4x³ - x² + 2x³ - 6x²    Simplifying like terms:

= -2x³ - 7x².
