comment Divisibility of polynomials in a subfield of a field.
maybe I can say that the coefficients of $h$ are obtained from the coefficients of $f$ and $g$ by operations $\pm, \times, /$ and this means that these coefficients have to be in $K$?

comment Degree of the map and path components
This circle goes around 0 once if $|a|<1$, if $|a|>1$ it doesn't go around 0 at all?
