What do you mean by "ring of polynomials of $a_1,\ldots a_n$?

@abiessu how do you prove this question using expasions?

comment Proof of that in an integral domain, every prime element is irreducible.
@EdwardPoon you have to use the fact $p$ is prime in the proof, but what you want to prove is $p$ is irreducible and to prove this you have to prove if $p=ab$, then $a$ or $b$ is unit.

@EdwardPoon yes, you are right. However, you want to prove that $p$ is irreducible. You already know that $p$ is prime.

@EdwardPoon Why do you like to analyse this case? you want to prove that $p$ is irreducible. If you prove the case for $px=ab$, you are proving $px$ is irreducible, instead of $p$.
