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.

#### Solution in text:

-14.1371669412r2+18.8495559215r=0 ... c=0; quadratic equation without constant term

Discriminant:
D = b2 - 4ac = 355.305758439
D>0 ... The equation has two distinct real roots

r1 = 1.33333333333
r2 = 0

P = {1.33333333333; 0}
