The lines p(p 2 + 1) x – y + q = 0 and (p 2 + 1) 2 x + (p 2 + 1) y + 2q = 0 are perpendicular to a common line for:
Text Solution
Verified by ExpertsThe correct answer is:
A
p(p 2 + 1) x – y + q = 0
(p 2 + 1) 2 x + (p 2 + 1) y + 2q = 0 are perpendicular
for a common line ⇒ lines are parallel ⇒ slopes are equal
∴ 
= – 
p = – 1
