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:

-2.2h2-h+230=0 ... quadratic equation

D = b2 - 4ac = 2025
D > 0 ... The equation has two distinct real roots

h1 = 10
h2 = -10.454545454545

P = {10; -10.454545454545}
