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.

Solution in text:

0.75r²-10.5r-335.25=0 ... quadratic equation

Discriminant:
D = b² - 4ac = 1116
D > 0 ... The equation has two distinct real roots

r₁ = 29.2710575
r₂ = -15.2710575

P = {29.2710575; -15.2710575}
