A) \[7x+8y+14=0\]
B) \[7x-8y+14=0\]
C) \[7x-8y-14=0\]
D) None of these
Correct Answer: C
Solution :
Equation of radical axis, \[{{S}_{1}}-{{S}_{2}}=0\] i.e., \[(2{{x}^{2}}+2{{y}^{2}}-7x)-(2{{x}^{2}}+2{{y}^{2}}-8y-14)=0\] \[\Rightarrow -7x+8y+14=0\], \[\therefore \ 7x-8y-14=0\].You need to login to perform this action.
