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

Please find all ordered pairs of integers (x,y) such that x^{2}+ 2x + 18 = y^{2}

2. Relevant equations

x^{2}+ 2x + 18 = y^{2}

3. The attempt at a solution

Im not sure on how to begin. I tried square-rooting the expression, to solve for y, turning it into y = [tex]\sqrt{x + 2x + 18}[/tex]. I would greatly appreciate any help to get me started on this problem.

Thanks!
