Hi,

Like the subject says, but take for example:

(2/(3x)) + (6/x) + (x/(x + 3))

Sending to the kernel simply gives:

20/3x + x/(3+x)

What I wanted/hoped for was the common-denominator version:

(3x^2 + 20x + 60)/(3x(x+3))

Is there any way to get Mathematica to give the one-denominator
version of sums of fractions?

thanks,

cdj
