Polynomial.quotient_mk_comp_C_isIntegral_of_isJacobsonRing

∀ {R : Type u_1} [inst : CommRing R] (P : Ideal (Polynomial R)) [hP : P.IsMaximal] [IsJacobsonRing R],
  ((Ideal.Quotient.mk P).comp Polynomial.C).IsIntegral

If R is a Jacobson ring, and P is a maximal ideal of R[X], then R → R[X]/P is an integral map.
