equation for pair of st lines passing through origin:


(y-m1x)*(y-m2x)=0   where m1 ,m2 are slopes of two lines


question is   6X^2 +2hxy +y^2=0


m1  /m2 = 1/2


asper equation of pair of st lines passing through origin


m1*m2 =6 ... m1/m2 =1/2.... -(m1 +m2)=2h


solve the above three equations and get the answer.......
