Quadratic equation calculator

Quadratic equation has the basic form: ax2+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:

27x2-35x=0 ... c=0; quadratic equation without constant term

D = b2 - 4ac = 1225
D > 0 ... The equation has two distinct real roots

x1 = 1.2962963
x2 = 0

P = {1.2962963; 0}
