Question

Please simplify

Answer 1

you need to use the chain rule...

Answer 2

Yes, \[\frac{ 1 }{ 2 }(2x-x ^{2})^{-.5}(2)(-2x)\]

Answer 3

Answer 4

Hmm looks very close anthony.
Your chain is a little bit off though:\[\Large\rm \frac{d}{dx}(2x-x^2)=(2-2x)\]You have an extra set of brackets that shouldn't be there.
