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:

-4x2+5x=0 ... c=0; quadratic equation without constant term

Discriminant:
D = b2 - 4ac = 25
D>0 ... The equation has two distinct real roots

x1 = 1.25
x2 = 0

P = {1.25; 0}
