A) \[2\alpha +10\beta +11=0\]
B) \[2\alpha -10\beta +11=0\]
C) \[10\alpha -2\beta +11=0\]
D) \[10\alpha +2\beta +11=0\]
Correct Answer: C
Solution :
Accordingly, \[{{\alpha }^{2}}+{{\beta }^{2}}-4\alpha -5={{\alpha }^{2}}+{{\beta }^{2}}+6\alpha -2\beta +6\] \[\Rightarrow 10\alpha -2\beta +11=0\].You need to login to perform this action.
