I'm supposed to differentiate [(sqrt(x))+1]^2/x

I thought this would be fairly straightforward even though I haven't learnt how to differentiate multiplications and divisions of functions.

So I developed [(sqrt(x))+1]^2 to end up with x+2(sqrt(x))+1, which gives me the three terms x/x + 2(sqrt(x))/x + 1/x, which differentiating separately gives me the final result:

-1/x(sqrt(x)) - 1/(x^2)

But this is incorrect apparently, where did I go wrong?
