Hi,

(x^2+3x-4)/(x-1)= (x+4)(x-1) /(x-1) = (x+4)



          x^2 + 5x -   15   R = 24

        __________________________

x + 2 | x^3 + 7x^2 -  5x - 6

      - (x^3 +  2x^2)

       ---------------

                5x^2 -  5x

             - (5x^2 +  10x))

                --------------

                         -15x - 6

                      - (-15x - 30)

                          --------

                                 24
