Main Question or Discussion Point

Hello! I have just a small question - does the theory of polynomials say something about their coefficients? I mean: is the polynomial with all the coefficients being imaginary still considered as a "normal' polynomial?

In some sense, it's possible to have polynomials over any mathematical object where multiplication and addition is defined. So, for example, one might have a polynomial over the real numbers (a.k.a. a real polynomial), over the complex numbers (a complex polynomial), the integers mod 17, or 7x7 matrices. When in doubt, it is always safe to specify what type of object is being operated with.

The notion of "normal" is basically a result of context. Real and complex polynomials are both very common. The others are more exotic.
