I'm using Mathematica 8. When using 'Together' on an expression the numerator
is always expanded, complicating the appearance of the final result:
In: Together[ (a+b)/d + ((a+b)*(e+f))/(d*g) ]
Out: 1/(d*g) * (a*g + b*g + a*e + b*e + a*f + b*f)
Instead, I'd much prefer the simpler form
1/(d*g) * (a+b)*(g+e+f)
What do I need to do to get the latter form? Thanks.
