You must have pressed the MODE key followed by SOLV , QUAD or SIMUL-2 or SIMUL-3 . If the calculator has these a programs they solve a Quadratic equation, a simultaneous system of two linear equations (SIMUL-2) . a system of 3 linear equations (SIMUL-3).
To use these solvers (IF YOU ARE INTERESTED), you select the solver you want and you will be prompted for a first coefficient (a, or a1). You enter the value and press the DATA key and you will be prompted for the next coefficient.
To exit the Solver mode press the MODE key followed by the key next to which there is DEC or >DEC. It might also be marked COMP.
Sorry, I do not have that very calculator but an other AUREX Scientific calculator (DS-752C).
