I think Diophantine equations are in Number Theory...

In any event. I am trying to solve $\displaystyle 25 n^2 + (10 a - 264) n - (3a^2 - 4a + 52) - p^2 = 0$ for n and p, where a is a constant positive integer.

I wasn't able to figure out how to do it by hand and I couldn't find a way to get W|A to understand the "a".

Any help is appreciated.
