Pesky remainder problem

  1. Dec 23, 2003 #1
    If p(x) = (x+2)(x+k) and if the remainder is 12 when p(x) is divided by x-1, then what is the value of k?

    I'm not sure if it is the right answer, but I think it is 3.

    After using long division, we get the remainder 3k+3, which equals 12, meaning k=3.

    Yes that is rite, found by long division or by saying that when x=1, expression =12 (remainder theorem or something like that)
