Break up the fraction

Simplify

------------------------

So hopefully you can see that simply subtracting 1 from will help us get to which turns into

------------------------

So let's apply this to the problem to get

Given

Subtract 1 from both sides

Turn the '1' on the left side into (y is nonzero)

Combine the fractions

------------------------

So is equal to where it is given that
