Equation of a circle circumscribing a triangle whose sides are L1=0;L2=0 and L3=0

Find the equation of a circle circumscribing the triangle whose sides are x=0, y=0 and lx + my = 1 . If l, m can vary so that l^2 + m^2 = 4l^2 m^2 , find the locus of the centre of the circle.

Equation of the circumcircle of a triangle formed by the lines L_(1)=0,L_(2)=0andL_(3)=0 can be written as L_(1)L_(2)+lamdaL_(2)L_(3)+muL_(3)L_(1)=0 , where lamdaandmu are such that coefficient of x^(2) =coefficient of y^(2) and coefficient of xy=0. If L_(1)L_(2)+lamdaL_(2)L_(3)+muL_(3)L_(1)=0 is such that mu=0andlamda is non-zero, then it represents
