Hi

 A = L*W

Question states***

 W = (2x^3-8x^2+2x+12)/ (x-2) = 2x^2 - 4x - 6    



       2x^2 -4x  - 6

       _______________________

x - 2 | 2x^3  -8x^2   +2x  +12

      - (2x^3 -4x^2)

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

                -4x^2 + 2x

             - (-4x^2 + 8x)

                ---------

                       -6x + 12

                    - (-6x + 12)

                       ---------

                             0
