%282x%5E3+%2B+6x-4%29+%2F+%28x%2B4%29
Probably the easiest way to divide is synthetic division. Synthetic division is set up to divide by (x-a) so we need to picture the denominator as: (x-(-4)):
-4 |   2    0    6    -4
----       -8   32  -152             
      ------------------
       2   -8   38  -156

So
%282x%5E3+%2B+6x-4%29+%2F+%28x%2B4%29+=+2x%5E2+-8x+%2B+38+%2B+%28-156%29%2F%28x%2B4%29
