A) \[(am+hl)x=(bl+hm)y\]
B) \[(am-hl)x=(bl-hm)y\]
C) \[(am-hl)x=(bl+hm)y\]
D) None of these
Correct Answer: B
Solution :
Let the equation of lines represented by \[a{{x}^{2}}+2hxy+b{{y}^{2}}=0\] be \[y-{{m}_{1}}x=0\] and \[y-{{m}_{2}}x=0\] and one diagonal AC be \[lx+my=1.\] Therefore \[{{m}_{1}}+{{m}_{2}}=\frac{-2h}{b}\]and \[{{m}_{1}}{{m}_{2}}=\frac{a}{b}\]You need to login to perform this action.
