Nonzero Polynomials

Hi all,

Can someone advise if part (a) is correct?

I am not sure how to do part (b).

Thanks

For part (b), you should prove that given any field, $F$, the polynomial ring, $F[x]$ is a euclidean domain. From this is easily follows that a polynomial of degree $n$ over any field has at most $n$ roots in that field. Hence, for part (b) the answer is no.
