Polynomial.rootSet
{T : Type w} →
[inst : CommRing T] → Polynomial T → (S : Type u_1) → [inst_1 : CommRing S] → [IsDomain S] → [Algebra T S] → Set SThe set of distinct roots of p in S.
If you have a non-separable polynomial, use Polynomial.aroots for the multiset
where multiple roots have the appropriate multiplicity.
