A) \[{{x}^{2}}+{{y}^{2}}\pm ax\pm ay+\frac{{{a}^{2}}}{4}=0\]
B) \[{{x}^{2}}+{{y}^{2}}+ax\pm ay+\frac{{{a}^{2}}}{4}=0\]
C) \[{{x}^{2}}+{{y}^{2}}-ax\pm ay+\frac{{{a}^{2}}}{4}=0\]
D) None of these
Correct Answer: C
Solution :
\[\Rightarrow \] \[{{\left( x-\frac{a}{2} \right)}^{2}}+{{\left( y\pm \,\frac{a}{2} \right)}^{2}}={{\left( \frac{a}{2} \right)}^{2}}\] \[\Rightarrow \] \[{{x}^{2}}+{{y}^{2}}-ax\pm \,ay+\frac{{{a}^{2}}}{4}=0\]You need to login to perform this action.
