Hi Fred,

Use e.g. the free symbolic CAS YaCAS, integrated in free EULER 2.11 (2.6 MB),
URL: http://mathsrv.ku-eichstaett.de/MGF/homes/grothmann/euler/
and write at the YaCAS-Prompt (you must append the two greater sign >> at the 
Euler Prompt > ):

>>> Simplify(Integrate(y,0,y-1/2) Integrate(x,1/2+y,0) 12*x*y*(1-y) ))

Screenshot appended.

Best
          Wolfgang
