Quadratic equation calculator

Quadratic equation has the basic form: ax2+bx+c=0
eq2
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.


Calculation:

s((9+s)+(4+s))=(9+s)(4+s) s236=0 s1,2=±36=±6 s1=6 s2=6 

Solution in text:

s2-36=0 ... b=0; pure quadratic equation

Discriminant:
D = b2 - 4ac = 144
D > 0 ... The equation has two distinct real roots

s1 = 6
s2 = -6

P = {6; -6}
