# Math Help - Implicit Differentiation Check

1. ## Implicit Differentiation Check

Can someone check my work? I keep getting a -y/x-y and not y/y-x. Even if i flip my answer i get y/y+x

Thanks

Your answer is equivalent to what your key gives as the answer, just written in a different form. Take your answer and multiply by 1 in the form:

$\frac{-1}{-1}$
