The formula ax2 + bx + c = 0 is called quadratic equation. The equation is not quadratic, if a=0.
The expression (b2- 4ac) is called discriminant. The discriminant provides information regarding the nature of the roots:
- 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".
