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:

n(n1)=552 n2n552=0  a=1;b=1;c=552 D=b24ac=1241(552)=2209 D>0  n1,2=2ab±D=21±2209 n1,2=21±47 n1,2=0.5±23.5 n1=24 n2=23   Factored form of the equation:  (n24)(n+23)=0 

Solution in text:

n2-n-552=0 ... quadratic equation

Discriminant:
D = b2 - 4ac = 2209
D > 0 ... The equation has two distinct real roots

n1 = 24
n2 = -23

P = {24; -23}
