Let $P(n)$ be an irreducible polynomial of degree $2$ over the positive integers. Show that thereDo there exist infinitely many positive integers $n$ such that $P(n)$ divides $n!$.?
Edit: motivation by examples:
A) $p(n)=n^2+1$ (true, $21^2+1$ divides $21!$).
B) $p(n)=n^2+n+1$ (true, $74^2+74+1$ divides $74!$).
