Dear Karan
If we have to find equation of circumcircle when the side of a triangle is given
L1 = 0, L2 = 0, L3 = 0
Equation of circul circle is:
L1*L2 + $\lambda$ L2* L3 + $\mu$ L3* L1 = 0
Where $\lambda$ and $\mu$ can be found out by
Putting the coefficient of x² and y² equal.
And also coefficient of xy should be 0.

Hope this helps
