(35s 42s/DM42 50G) Quadratic formula

[PedroLeiva]

I tried this examples from HP 25 Application Program Manual:

ax2 + bx + c = 0

Examples
1 . X2 + X - 6 = 0
2. 3 X2 + 2x -1 = 0
3. 2X2 - 3x + 5 = 0

Solution
1. D = 6.25
Xl = -3.00
X2 = 2.00
2. D = 0.44
Xl = -1.00
X2 = 0.33
3. D = -1.94
Xl , X2 = 0.75 ± 1.39 i

For the first case with your program: x1= -3, x2= 3; the rest INVALID DATA
The program looks nice, but some corrections have to be made. Pedro
