No, this is not a Homework problem.

I got this doubt while reading Chapter 3 of Ian Stewart's book on
Galois Theory - P43 that is on Reduction Modulo p.

I have just asked for a url link to a standard material ; I wonder
what / how it makes you think that it could a Homework problem - I am
not asking for any solution to an exercise problem seeking specific
solutions.
