When I entered the equation 1/(x+1)^2 into a derivativecalculator, it told me the derivative should be 1/(x^2 + 2x +1),but I don't think I got that result.

I inserted myquestion as a picture instead. I didnt know how to write out theequations here.
I thought the answer was 1/15x^2 + 1 but I think that is onlythe derivative. How do I find this using differentiatingimplicitly? Do you changet he x and y?
