The condition that the line lx+my+n=0 to touch the parabola `y^(2)=4ax` is

A : The condition that the line x/p+y/q=1 to be a tangent to the parabola y^(2)=4ax is ap+ q^(2) =0. R: The condition that the line lx+my+n=0 may touch the parabola y^(2)=4ax is am^(2) = In

obtain the condition that the line lx+my+n=0 will touch the parabola y^2=4ax .

The condition that the line lx +my+n =0 to be a normal to y^(2)=4ax is

The condition that the line lx +my+n =0 to be a normal to y^(2)=4ax is

The line lx+my+n=0 is a normal to the parabola y^(2)=4ax if

If the line lx + my +n=0 is a tangent to the parabola y^(2)= 4ax , then-

The line 4x+6y+9 =0 touches the parabola y^(2)=4ax at the point

The line 4x+6y+9 =0 touches the parabola y^(2)=4ax at the point

The condition that the line ax + by + c =0 is a tangent to the parabola y^(2)= 4ax is-
