Hi all, Just wondering how I would go about finding roots of an polynomial, say t^2 +2, over a quotient ring, say Z/5Z[x] / <x^2+2>, in Mathematica? The modulus option in Reduce is only for integers, and I've had trouble finding anything relevant in the finite fields package... anyone know if this can be done in Mathematica? Thanks, Julian
