# Quadratic equation calculator

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:

2z2+3z+1=0 ... quadratic equation

Discriminant:
D = b2 - 4ac = 1
D>0 ... The equation has two distinct real roots

z1 = -0.5
z2 = -1

P = {-0.5; -1}
