If an angular bisector of the coordinate axes is one of the lines of \(x^2+2 a x y+3 y^2=0\), then sum of all possible values of \(a\) is
- A -1
- B 1
- C 0
- D -2
Answer & Solution
Correct Answer
(C) 0
Step-by-step Solution
Detailed explanation
Bisectors of the angle between the coordinate axes are \(y= \pm x\) Then, \(x^2+2 a x( \pm x)+3 x^2=0\)…
