A) \[{{x}^{2}}+{{y}^{2}}+22x+9=0\]
B) \[{{x}^{2}}+{{y}^{2}}+22x-9=0\]
C) \[{{x}^{2}}+{{y}^{2}}+22y+9=0\]
D) \[{{x}^{2}}+{{y}^{2}}+22y-9=0\]
Correct Answer: C
Solution :
Using\[{{S}_{1}}+\lambda {{S}_{2}}=0\], but its centre is on y-axis. i.e., \[-8-4\lambda =0\] or\[\lambda =-2\]. Hence required equation is\[{{x}^{2}}+{{y}^{2}}+22y+9=0\].You need to login to perform this action.
