A) \[x+10y+2=0\]
B) \[x+10y-2=0\]
C) \[x+10y+8=0\]
D) \[x+10y-8=0\]
Correct Answer: B
Solution :
Radical axis of given circles is \[\left( -\frac{7}{3}+3 \right)\,x+\left( \frac{8}{3}+4 \right)\,\,\,y+\frac{11}{3}-5=0\] \[\Rightarrow \] \[2x+20y-4=0\]\[\Rightarrow \]\[x+10y-2=0\].You need to login to perform this action.
