Polynomial division should yield a remainder of 0. This works like regular long division.

               x^2      x        -6
          ---------------------------------------- 
          |
3x-2      |   3x^3     x^2       -20x       12
          |   3x^3    -2x^2
          |________________
               0      3x^2      -20x
                      3x^2      -2x
                     _________________
                       0        -18x        12
                                -18x        12
