comment Infinite Sum of 1/Polynomial
If you're implying that $\sum a_n \sum b_n = \sum a_n b_n$, note that this is wrong.

comment Show that polynomial is reducible
@user201917 This method becomes insufficient. In general, a polynomial of degree $> 3$ can be reducible without having roots. Take the product of two irreducible polynomials of degree $2$ for example.

I assume $\mathbb N$ has the discrete topology? In this case, convergent sequences in $\mathbb N$ are eventually constant. This makes the question easy.

Is the field here $\mathbb R$ or some algebraically closed field? Doesn't your reference mention Hilbert's Nullstellensatz?
