Oh... wow okay so x could = m or -m both of which are integers. That makes sense. I don't understand how to prove that any other solution would be irrational :/
Homework Statement
Suppose a, b ε Z. Prove that any solution to the equation x^3 +ax+b = 0 must either be an integer, or else be irrational.
Homework Equations
Not sure if this is right but x = m / n where m divides b and n divides 1
