Quadratic equation has the basic form:
$a{x}^{2}+bx+c=0$

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.

## Calculation:

#### Solution in text:

-u2+54=0 ... b=0; pure quadratic equation

Discriminant:
D = b2 - 4ac = 216
D>0 ... The equation has two distinct real roots

u1 = 7.3484692283495
u2 = -7.3484692283495

P = {7.3484692283495; -7.3484692283495}
