Calculateur de Quadratic Discriminant
Calculate the discriminant of a quadratic equation ax^2 + bx + c.
Formula and method
This calculator computes Discriminant directly in your browser without sending data to an external server.
Mathematical formula
- Discriminant:
b × b-4 × a × c
Variables and parameters
- a (a): default value 1.
- b (b): default value -5.
- c (c): default value 6.
Some formulas are undefined for certain input combinations (such as division by zero or logarithms of non-positive numbers). In those cases the live tool displays an alert instead of NaN.
