In GeoGebra 6, also:

Select Advanced in the Text tool dialog window, then select the αβγ tab to open a list of useful mathematical symbols. Select the desired one to insert it in the Text

In GeoGebra 5,

select Symbols in the Text tool dialog box, then select ×÷− to open a list of useful mathematical symbols. Select the desired one to insert it in the Text

Use LaTeX: type

\pm

in a Text tool dialog window. Same in an input box, only if it's linked to a LaTeX text, but using LaTeX commands in input boxes can be tricky.
