    Remainder Theorem

    "Use the remainder theorem to find the remainder quickly when the polynomial on the left is divided by the linear binomial on the right"

    1. x^5 - 3x^2 + 14 by (x+2)

    2. x^51 + 51 by (x+1)


    I have absolutely no clue how to either of these...Thanks

    for the first one you substitue x=-2 because of some reason that i can't remember and for the second you substitue x=-1 for the same reason, it should give you the remainder.

    With that type of atitude I can solve the Birch-Swinnerton Dyer conjecture.

    In my text book it says:

    If a polynomial f(x) is divided by (ax - b) then the remainder is f(b/a)

    in your case:
    Compare (x + 2) which is the same as (1x + 2) to (ax - b), so a=1, b=-2 and the remainder is f(-2/1)

    Does that help?
