     Finds a quadratic equation from 3 points an records the result to a listbox, which can then be saved. Added line thickness and colour selection for curve and points. Also can display more than one curve. Added a sqaured to the equation in the listbox and also replaced +- with just a negative. Thanks to Paul Bahlawan for fixing the overflow/curve bounds problem. Thanks to DreamVb for the colour palette selector. Also used McListbox (Heriberto Mantilla Santamaria and Jim Jose from years back).

Hi Eddie,
Try this in Private Sub Get_Equation()
Picture1.CurrentX = -9.95
Y = C
Picture1.CurrentY = -A * -9.95 ^ 2 + B * -9.95 + C
For X = -9.95 To Picture1.ScaleWidth Step 0.1
