Hey,
I don't know how to do the following question:
For which integers does divide in ?
I'm afraid I'm not entirely sure what to do for this question. I think my confusion for this question begins with the definition of . Is the ring of algebraic integers? Should I be looking an integer that makes the 2 above polynomials equal to 0, then find out what integer multiples make the 2 polynomials equal to 0 as well?
Thanks for your time.
