I'm stuck for part ii). For part i) I put "If the equation a^2x+bx+cx has at least one integer solution, then either a,b or c is even"
I'm not too sure if it's right or not.

I *think* you would start by basically putting in the quadratic formula:
then since x is divided by 2a, and x is an integer, the numerator must be even and = 2xa (which proves that at least b, a or c is even). i'm not too sure though
