Introduction to Rings and Fields- Help

[Palindrom]

I really don't wanna define a homomorphism like
psi(p(x))=p(x-1+I
I'm looking for another way to solve that next question:

Show that Q[x]/(x-1) is isomorphic to Q[x]/(x-2).
Any ideas?
Thanks in advance.

You could show they're both isomorphic to a third ring...

Of course, they're both isomorphic to Q... I really shouldn't do HW at 11 pm... Thanks!
