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.

Calculation:

Solution in text:

-X²+2X=0 ... c=0; quadratic equation without constant term

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

X₁ = 2
X₂ = 0

P = {2; 0}
