The line lx+my+n=0l x+m y+n=0 is a normal to the parabola y2=4axy^2=4 a x, if
View answer and explanation
Correct option: A
al(l2+2m2)+m2n=0a l\left(l^2+2 m^2\right)+m^2 n=0
Option A (al(l2+2m2)+m2n=0a l(l^2+2 m^2)+m^2 n=0) is correct because it represents the condition for the line lx+my+n=0l x+m y+n=0 to be a normal to the parabola y2=4axy^2=4 a x.
