Homework Statement
Find all solutions in Z12 to the equation X^2=4Homework Equations
The Attempt at a Solution
This is my attempt, since it is in Z12, i wrote X^2=4(modulo 12) and by this the answers are trivial, X= 2, 4,8,... and also -2,-4...this just seems to easy so i was wondering if i was doing it wrong
