          2 | 4  -1  -7  18  0
            |   __ 8__14__14__64__   
 
              4   7   7  32   64

So you should get 4x%5E3%2B7x%5E2%2B7x%2B32%2B64%2F%28x+-+2%29
You subtracted 18 and 14, instead of adding, and theres a 0 thats in the place of ax^0. So you missed one step. But other than that you got it. You can check these by going to this site:
