Question 73067
<pre>


          2 | 4  -1  -7  18  0
            |   __ 8__14__14__64__   
 
              4   7   7  32   64     
                                     </pre>

So you should get {{{4x^3+7x^2+7x+32+64/(x - 2)}}}
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:
