I should say that this argument is quite close to the proof by Victor Protsak, the main difference being mention of Euclidean division: to me the right hand side just begs to be interpreted as a coefficient of a Euclidean quotient by $X-A$ (more generally Horner-scheme sub-expressions do). By the way, the Cayley-Hamilton theorem can be obtained more directly here by interpreting the fact that the remainder is 0. | |
