Question 32153
You started with "3" in the numerator and "6" in the 
denominator.  You can reduce that to 1/2.
So you have (1-sqrt3)/2
1-sqrt3 is > 1-sqrt4=-2
Since the numerator is greater than -2 
dividing by "2" gives you a number greater
than -1.
Maybe it is around -0.5
Actually it is around -0.36
