I have one more problem...
I want to find all rings Zn, such the polynomial x+2 divides polynomial (x^5)-10x+12.
Could anybody help me?
Thanks, this is a new topic for me...

of course, -2 is root of that polynomial...I know. I think it should work, that it is divisible in any ring, but I canīt find the reason...
Zn isnīt a subring of Z, or am I wrong??
can you give me one more hint please? I am really trying to find out why it is so in any ring, but Iīm afraid Iīm not able to do it now. I have passed an exam (not algebra) few hours ago, Iīm exhausted, but I really want to do my homework...
