equation and press [WHITE SHIFT][7] or the S.SLV key, then press
SOLVEVX (second soft key from the right) and voila! both roots are on
level 1 (assuming you are in RPN mode). If you are not in RPN mode, I
highly recommend you start, to get the full good out of your 50g.

Ex: X^2+5X+6  ENTER  SOLVEVX
The display shows 1: {X=-2 X=-3}
