The algebraic solution is in the form

A = F(a,b)
B = G(a,b)

Where A,B,a,b are all integers with some of them non-zero.
In the general case they are all non-zero.
Your task is to find the functions F(), G().

functions?

F(a,b) = sqrt(a^2+b^2)
G=F

that seems way too easy

sqrt(a^2+b^2) isn't an integer except in a handful of special cases.

There is a closed form exact algebraic solution for all a,b.
