The given polynomlal x⁴+3x³-6x²-12x-8 will be divided by x-3 so we need to find the remainder:-

x-3) x⁴+3x³-6x²-12x-8 ( x³-6x²+12x+24

      x²-3x³

    _______________

            6x³-6x²-12x-8

            6x³-18x²

________________________

                   12x²-12x-8

                   -12x²-36x

  _____________________

                            24x-8

                            24x-72

_______________________
