Two lines are given by

(x-2 y)^2+\lambda(x-2 y)=0

. The value of

|\lambda|

so that the distance between them is 3 , is

View answer and explanation

Correct option: C

3 \sqrt{5}

The correct answer is C (

3 \sqrt{5}

) because the distance between the parallel lines is given as 3, and solving for
