    usually to find P(r) you need to plug in P(r)

    the remainder theorem says, if you divide P(x) by x-r the remainder becomes P(r)

    so all you do is synthetic division to find the remainder

    2| 2 -3 0 0 6 0 4 2 4 8 --------------- 2 1 2 4 14 <- remainder is 14 ^^^^^^^^^^^ 2r^3 +r^2 +2r +4 + 14(r-2)
