<pre>

-2[(-3+2)(-3+1)]      -2[(-3+2)(-3+1)]
----------------- =  -------------------
-4-1 - (-1)              -4-1 +1



                       -2[(-1)(-2)]
                  =  ----------------
                           -4


                       -2[2]
                  =  ----------
                        -4


                        -4
                  =  ----------
                        -4


                  = 1
