@Moron: It's a part of the fundamental theorem. Consider this question as answered.

@Moron: I'm not (yet) in university. This isn't homework. Just asking this as a part to proof my last question. I'm asking this because I didn't knew, that this is a fundamental theorem of algebra.

comment How to prove the equality $\sum_{j=0}^n (x)^j (-1)^{n-j} \left\{{n \atop j}\right\} = x^n$?
Is your $(x)^j$ the same as $x^\overline{j}?$

@Jason DeVito: $a_k$ and $b_k$ are just coefficients. They're independent of $x$.

This proof is the easiest to understand for me. Thank you.

Uhhh... That's difficult. Thanks for this link.
