If "`((1)/(2),2)`" is one extremity of a focal chord of parabola "`y^(2)=8x`" then other extremity is

If (-1,-2sqrt2) is one of exteremity of a focal chord of the parabola y^(2)=-8x, then the other extremity is

(1/2,2) is one extremity of a focal of chord of the parabola y^(2)=8x The coordinate of the other extremity is

If the point (at^(2),2at) be the extremity of a focal chord of parabola y^(2)=4ax then show that the length of the focal chord is a(t+(1)/(t))^(2)

The point (1,2) is one extremity of focal chord of parabola y^(2)=4x .The length of this focal chord is

If (x_(1),y_(1)),(x_(2),y_(2)) are the extremities of a focal chord of the parabola y^(2)=16x then 4x_(1)x_(2)+y_(1)y_(2)=

If (t^(2),2t) is one end ofa focal chord of the parabola,y^(2)=4x then the length of the focal chord will be:

If the point ( at^2,2at ) be the extremity of a focal chord of parabola y^2=4ax then show that the length of the focal chord is a(t+t/1)^2 .

If (x_(1),y_(1)) & (x_(2),y_(2)) are the extremities of the focal chord of parabola y^(2)=4ax then y_(1)y_(2)=
