Have you mis-typed something? Your conditions mean that N = k/D
where k and D are already polynomials. You could choose B = k and A
= D, or multiply both k and D by any polynomial you liked.

For example, if k = 1 and D = x + 1
so N = 1 - x + x^2 - x^3 + ....
then you could have
B = 1, A = x + 1, or
B = x^2 - 7, A = (x + 1)(x^2 - 7),
etc. etc.

Perhaps you meant something different.
