Hey all! Searched for the solution all over the net but no results as for now :\

Problem: Need to solve the equation $\displaystyle y^2=x^3-5*x+3$ by modulo 11 using Maxima with particular x (later there will be loop for random x's).

Code i use to do this:

modulus:11

solve(y^2=x^3-5*x+3,y), x=0

So, what i get is $\displaystyle y= +- sqrt(3)$ and that isn't right. It's like Maxima didn't notice modulo at all. Any ideas?
