(3x^2 - 7x -4) - (6x^2 -6x +1)
It's a polynomial
I think the answer is D or C, but I'm not sure which one. Help please
A. 3x^2 - 13x - 5
B. 9x^2 - x + 5
C. -3x^2 -13x + 5
D. -3x^2 -x -5
Thank you!

To find the subtraction of the given polynomials, you need to distribute the negative sign to each term in the second polynomial and then combine like terms.
Let's break it down step by step:
First, distribute the negative sign to each term in the second polynomial:
(3x^2 - 7x - 4) - (6x^2 - 6x + 1) = 3x^2 - 7x - 4 - 6x^2 + 6x - 1
Now, let's combine like terms:
3x^2 - 7x - 4 - 6x^2 + 6x - 1 = (3x^2 - 6x^2) + (-7x + 6x) + (-4 - 1) = -3x^2 - x - 5
Therefore, the correct answer is D. -3x^2 - x - 5.
