Hi,

I have solved some equations using solve() which does some manipution then takes a few positive and negative sqrts and then some more manipulation. There are several sets of solutions, but it's not obvious which ones correspond to which sign of sqrts. Is there an easy way I can make solve() only take positive square roots?

Thanks! And let me know if more info is needed.
