I choose A

anonymous · Answer

I'M SORRY IT'S C, I didn't see the "binomial" part

anonymous · Answer

I believe it to be C at least

anonymous · Answer

C is correct. It has 2 terms and has a higher exponential power than D. :)

Awesome:
Find the quotient of the quantity  $$\frac{ -12x^3+21x^2-6x }{ -3x }$$

 -4x^2 - 7x + 18

 4x^2 + 7x + 18

 -12x^3 + 21x2 + 2

 4x^2 - 7x + 2
