# Math Help - Can someone remind me how to isolate y in this type of problem?

1. ## Can someone remind me how to isolate y in this type of problem?

I know I'm going to kick myself for this, but can someone remind me how to isolate and solve for y in this type of problem:

$y^2 + y = x^2 - 4$

2. Have you considered the Quadratic Formula or Completing the Square?

3. Ah, yes I was right about kicking myself. Aside from being very rusty, I got confused because it looks like there are two seperate equations - one for each variable. Thank you for that. I shall now beat myself soundly.
