Question 347726
<pre>
      x^2  + 2x    +  4
      ________________________
x-1  /x^3  +  x^2  +  2x  -  4
    -(x^3  -  x^2)
     ------------
             2x^2  +  2x
           -(2x^2  -  2x)
             -----------
                      4x  -  4
                    -(4x  -  4)
                      --------
                             0

So {{{(x^3+x^2+2x-4)/(x-1) = x^2 + 2x + 4}}}
