Quadratic equation calculator

Quadratic equation has the basic form: ax2+bx+c=0
Enter the quadratic equation's coefficients a, b, and c of 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:

2x2-7x+3=0 ... quadratic equation

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

x1 = 3
x2 = 0.5

P = {3; 0.5}
