Quadratic equation calculator

Quadratic equation has the basic form: $a{x}^2+bx+c=0$
Enter the quadratic equation's coefficients a, b, and c of its basic standardized form. A solution of quadratic equations is usually two different real or complex roots or one double root — the calculation using the discriminant.

Solution in text:

66x²-66.09=0 ... b=0; pure quadratic equation

Discriminant:
D = b² - 4ac = 17447.76
D > 0 ... The equation has two distinct real roots

x₁ = 1.0006816
x₂ = -1.0006816

P = {1.0006816; -1.0006816}
