Let p be a prime number. Let Zp denote the field of integers modulo p. Determine the(adsbygoogle = window.adsbygoogle || []).push({});

number of points (x, y) with x, y in Zp such that y^2 = x^3 + x^2.

I just don't really have any idea how to approach this; the last problem was to find all rational points on the above curve, which I did, but I'm not quite sure where to start with this one.
