    When \(f(x)\) is divided by \(x - k\), then the remainder is \(f(k)\)

    That is, you just have to replace \(x\) with \(k\).

    Yeah I got it itz when f(x) is divided by x−k, then the remainder is f(k)

    \[(-x^4 +2x^3 + x^2 -x -4)/(x-4)\] my answer is -120 I just got confused with this one because of -x^4 :)

    \(-x^4\) is like finding \(x^4\) then putting the negative sign.
