What if $n$ is not a natural number?

comment Type of isomorphism
There is always the natural map $$K\ \longrightarrow\ \operatorname{End}(M):\ x\ \longmapsto\ (m\ \longmapsto\ xm),$$ which is a morphism of $K$-modules, but this is rarely an isomorhism.

If $k=0$ then the polynomial is not quadratic. Does it have equal zeroes then?

The correct radius of the sphere is $\tfrac{3}{2\sqrt{2}}$ units. (Because I felt like it).
