QUADRATIC EQUATIONS SOLVER

X2+ X+ =
X1=?
X2=?

This app works on any combination of Decimals, Fractions and Mixed Numbers. Select Fractions or Decimals, enter the coefficients and click on SOLVE button. Following rules apply:

If Text box A is empty, system will assign 1 to A, so the Equation will look like: of x2+Bx+C=D.
If Text box B is empty, system will assign 0 to it, so the Equation will be like: Ax2+C=D.
If Text box C is empty, system will assign 0 to it, so the Equation will be like: Ax2+Bx=D.
Equation Ax2-Bx+C=D should be entered as Ax2+(-B)x+C=D.

QUADRATIC EQUATIONS

Quadratic Equation: >Ax2+Bx+C=0 has general solution:

x1= -(B+SQRT((B)2 - 4AC))/2A;
x2= -(B-SQRT((B)2 - 4AC))/2A;

where both roots could be Real or Complex numbers. If A=0 the equation transorms to the linear one.
