If the lines \(x^2+2 x y-35 y^2-4 x+44 y\) \(-12=0\) and \(5 x+\lambda y-8=0\) are concurrent, then \(\lambda\) equals
- A \(0\)
- B \(1\)
- C \(-1\)
- D \(2\)
Answer & Solution
Correct Answer
(D) \(2\)
Step-by-step Solution
Detailed explanation
Given line, \(x^2+2 x y-35 y^2-4 x+44 y-2=0\) \(\Rightarrow \quad(x+7 y-6)(x-5 y+2)=0\) \(\Rightarrow x+7 y-6=0\) and \(x-5 y+2=0\) and \(5 x+\lambda y-8=0\) are concurrent.…
