that really depends a lot on how you will use the result. You could save 
your expressions to package files as well (see the documentation for 
Save and Put), which would be somewhat more portable among different 
computers and Mathematica-versions.

You could also directly write Mathematica notebooks containing formatted 
expressions from the kernel, e.g. like this:

expr=a^2+b^2;

Put[
Notebook[{Cell[BoxData[ToBoxes[expr]],"Output"]}],
ToFileName[{$HomeDirectory},"result.nb"]
]

It's not too difficult to create more fancy notebooks with sections and 
multiple cells containing different expressions. See 
tutorial/NotebooksAsMathematicaExpressions if you think this approach is 
what you need. Honestly, I think saving the expressions to .mx or 
package files will be more useful for most use cases, since it's easier 
to load them for any post processing you might want to do with them.

hth,
