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.......
