Quadratic equation calculator

Quadratic equation has the basic form:

a x^{2} + b x + 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.

-u²+19u+640000=0 ... quadratic equation

Discriminant:
D = b² - 4ac = 2560361
D > 0 ... The equation has two distinct real roots

u₁ = 809.5564043
u₂ = -790.5564043

P = {809.5564043; -790.5564043}
