PolynomialQuotientRemainder returns a list with the quotient in the first position and the remainder in the second. You only asked for the remainder, that his why I chose the second entry of that list.

Thanks, it worked! But what does the [[2]] for?
Hi,
what about
PolynomialQuotientRemainder[x^3 + 6 x^2 + 13 x + 9, x^2 + 2*x + 1, x][[2]]
Cheers, Marco
