Hey maple gurus

when i solve and equation with two real roots (1 positive and 1 negative roots), how do i automatically pick out the postive solution?

As you can see from the attached file, i used sort command to order it, and it works for examples1 and 2, but not for 3.

i guess i could use Abs cmd.....
