Question

Guys plz answer this one

Answer 1

Answer:

Option A is correct

Step-by-step explanation:

If they are perpendicular to a common line then they must be parallel to each other.

m 1 =p(p 2 +1)

m 2= (p ^2 +1)

(p^2+1) 2=−(p ^2 +1)

m 1 =m 2

p(p2 +1)=−(p 2 +1)

∴p=−1

Hence The lines are perpendicular to a common line forexactly one value of p
