Given p(x) = x^3 - 6x^2 + 2x - 4.

Given g(x) = -3x/2 + 1

                   -2x^2/3  +  32x/9  +  28/27
           ---------------------------------------------------
-3x/2)  x^3    -     6x^2     +     2x      -    4

            x^3    -     2x^2/3

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

                       -16x^2/3      +   2x     -     4

                        -16x^2/3      + 32x/9

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

                                            -14x/9    -   4

                                            -14x/9    +  28/27

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

                                                           -136/27



Therefore Quotient = -2x^2/3 + 32x/9 + 28/27 and remainder = -136/27

f(x) = 2x^3 + 3x^2 - 11x - 3.

g(x) = (x  +1/2)



                  2x^2 +  2x - 12
            --------------------------------------
x + 1/2) 2x^3  +   3x^2  -   11x   -  3

             2x^3  +   x^2

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

                           2x^2   -   11x   -   3

                           2x^2   +   x

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

                                        -12x   -   3

                                        -12x   -    6

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

                                                      3.


Therefore Quotient = 2x^2 + 2x - 12 and remainder = 3.
