Hi;

No hocus pokus at all. In integer division we have a quotient and a remainder. For instance 17 / 6 = 2 with a remainder of 5. This is what division of polynomials uses. We expect the quotient and the remainder to also be polynomials.

Are there any implicit assumptions about k and a? Do they have to be integers?

Re: Oral puzzles

Nope, but we are given that the remainder is of the form x + a.
