PELL’S EQUATION, I 1. Introduction − dy For d in Z
... reducing both sides mod 5 to get x2 ≡ 6 mod 5, since that congruence has a solution so there is no contradiction. Reduce mod 3 instead: the equation becomes x2 − 5y 2 ≡ 0 mod 3, or x2 ≡ 5y 2 ≡ 2y 2 mod 3. This too has a solution, namely (0, 0), so it doesn’t seem like progress has been made. But thi ...
