Quadratic equation calculator

Quadratic equation has the basic form:
ax2+bx+c=0ax^2+bx+c=0

eq2
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:

2p2-300p+6250=0 ... quadratic equation

Discriminant:
D = b2 - 4ac = 40000
D>0 ... The equation has two distinct real roots

p1 = 125
p2 = 25

P = {125; 25}
