(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

Find y" in terms of x and y:

y^2 + 2y = 2x + 1

2. Relevant equations

N/A

3. The attempt at a solution

I found the first derivative:

y^2 + 2y = 2x + 1

2yy'+2y'=2

2y'.(y+1)=2

y'=2/2(y+1)

y'=1/(y+1)

But I'm having trouble moving on from there.
