If the line is one of the bisectors of then value of
- A
- B
- C
- D
Answer & Solution
Correct Answer
(A)
Step-by-step Solution
Detailed explanation
Given: x2+4xy-y2=0 This is the equation of pair of straight lines so comparing it with ax2+2hxy+by2=0 we get, a=1, b=-1, h=2 As we know the equation of the bisector is given by, x2-y2a-b=xyh ⇒x2-y21--1=xy2 ⇒x2-xy-y2=0 As y=mx is one of the bisector…
