Quadratic Equation Calculator

A quadratic equation has the basic form: ax2+bx+c=0
eq2
Enter the coefficients a, b, and c of the quadratic equation in its basic standardized form. The solution of a quadratic equation usually consists of two distinct real or complex roots, or one double root — calculated using the discriminant.


Calculation:

45(12+v)=(8(12+v)45)(12v) 8v272=0 8=23 0=0 72=2332 GCD(8,0,72)=23=8  v29=0 v1,2=±9=±3 v1=3 v2=3 

Solution in text:

8v2-72=0 ... b=0; pure quadratic equation

Discriminant:
D = b2 - 4ac = 2304
D > 0 ... The equation has two distinct real roots

v1 = 3
v2 = -3

P = {3; -3}
