Hi all,

here is my problem. I have the following system :

$\displaystyle S \left\{\begin{array}{cc}a^2 - ab + n = 0

\\a^2 - ac - n = 0\end{array}\right.$

Where $\displaystyle a$, $\displaystyle b$ and $\displaystyle c$ areintegerunknowns and $\displaystyle n$ is any integer value (known)

Is there anygeneralway to solve such equations quickly (for all three unknowns) ? Thanks a lot !
