Try executing

$PrePrint = InputForm

Then all text output will appear the same way it would be typed as a command,  
i.e. on a single line.

3 x^2

A variation on this is to use

$PrePrint = StringReplace[ToString[InputForm[#]],"*"->" "]&

This will replace the asterisk for multiplication with a space.
If you don't even want a space, remove the space from the between
the quotes in this command.
