I assume the problem is:
Express f(x) in the form f%28x%29=q%28x%29%28x-k%29%2Br for f%28x%29+=+-3x%5E3+%2B+5x+-6 for k=+-1

The easy way to do this is with synthetic division:
-1 |   -3   0   5   -6
----        3  -3   -2              
      ----------------
       -3   3   2   -8

So
f%28x%29+=+%28-3x%5E2+%2B3x+%2B+2%29%28x+-+%28-1%29%29+%2B+-8
