Quadratic equation calculator

Quadratic equation has the basic form:
ax2+bx+c=0

eq2
Enter the coefficients a, b, c of quadratic equation in 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

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

h1 = 10
h2 = -10.454545454545

P = {10; -10.454545454545}
