Calculate the discriminant quadratic equation online calculator

Online calculator which helps you calculate the discriminant of the quadratic equation.

The discriminant of the equation gives the number of the roots and nature of roots of an equation, the discriminant is equal to zero only when the polynomial has multiple roots.
The discriminant is a symmetric polynomial in the roots of a polynomial and is therefore a polynomial from its coefficients; moreover, the coefficients of this polynomial are integers, regardless of extension, which are the roots.

Quadratic equation, ax2 + bx + c = 0:
x2+ x+ =0

The value of the discriminant (Δ):
