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

The line lx + my + n = 0 will touch the parabola y^(2) = 4ax if am^(2) = nl .

If the straight line lx + my=1 is a normal to the parabola y^(2)=4ax , then-

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

Statement 1: The line ax+by+c=0 is a normal to the parabola y^(2)=4ax. Then the equation of the tangent at the foot of this normal is y=((b)/(a))x+((a^(2))/(b)). Statement 2: The equation of normal at any point P(at^(2),2at) to the parabola y^(2)= 4ax is y=-tx+2at+at^(3)

If the striaht line lx+my=1 is a normal to the parbaola y^(2)=4ax then show that, al^(3)+2alm^(2)=m^(2)

The st line lx+my+n=0 will be a tangent to the parabola y^(2)=4bx if

The line sqrt(2y)-2x+8a=0 is a normal to the parabola y^(2)=4ax at P ,then P=

The line sqrt(2)y-2x+8a=0 is a normal to the parabola y^(2)=4ax at P .then P =
