Equation

[fredrick75]

Hello,

There is a method to solve this kind of equation?

[FONT=MathJax_Math]root square of (a+x²) = y[/FONT]

I want to find the first positive integer solution.

Exemple : root square of (91 + 3²)=10

a x y must be integer.

Thank's

Since a must be positive, y is greater than x. So choose x and y then what is a?
