Polynomial Division

  1. Jul 20, 2008 #1
    1. The problem statement, all variables and given/known data
    The remainder is 3 when 4x^2 + 9x + k is divided by x-1
    Im suppose to find the K. Im just confused because this question they give me the remainder..so what am i suppose to do with it?

    Perform the usual operation, continue bringing k down and then at the end just solve for k by setting it equal to what your remainder should be.

    You could also use the fact that when a polynomial, P(x), is divided by x- a, the remainder is exactly P(a). You don't need to do any division at all.
