I think he was general. Anyway from memory:
Mathematica returns a list
{{solution-1, condition-1},........,{solution-n, condition-n}}
unless you passed an assumption to the command.
Command[expression,Assumptions->{some list}]
Actually Mathematica is a bit inconsistent there. The keyword
Assumptions can only be used in certain command (Integral
comes to mind but I am not sure that's the only one), while
some other like the Simplify familly don't (I am pretty sure):
Simplify[expr,{some assumptions}]
