AP calculus help! (my solution provided)

[farealol]

I tried to find the derivative of this function but the answer is strange. It doesn't seem like a final answer.

I am always not sure about my answer when I don't have a number for it.. Thank you for any help provided!

Why would you use the quotient rule if the numerator is a constant?

Everything you wrote seems correct. The question is whether or not you answered the question. Why do you think your answer is not correct?
