### Quadratic Equation

The formula **ax ^{2} + bx + c = 0** is called quadratic equation. The equation is not quadratic, if a=0.

The expression

**(b**is called discriminant. The discriminant provides information regarding the nature of the roots:

^{2}- 4ac)- If greater than zero, the equation has two solutions with distinct real numbers;

- If less than zero, the equation has no real solutions;

- If equal to zero, the equation has two solutions and equal roots.

Enter data for the coefficients:

**a**,

**b**y

**c**. For positive numbers, the positive sign is dispensed. Use the point as decimal separator. Ex. For the number 5,152.47 enter 5152.47; The results will be displayed automatically after click on

**"Calculate"**.
