When we divide a polynomial, p(x) by some divisor polynomial d(x), we will get a quotient polynomial q(x) and possibly a remainder r(x). In other words, p(x) = d(x)q(x) + r(x) Because of the division, the remainder will either be zero, or a polynomial of lower degree than d (x). how many people speak english in austria
