f the normal at the point `P (at_1, 2at_1)` meets the parabola `y^2=4ax` aguin at `(at_2, 2at_2),` then

" If the normal at the point " t_(1)(at_(1)^(2),2at_(1)) " on " y^(2)=4ax " meets the parabola again at the point " t_(2) " ,then " t_(1)t_(2) =

The normal drawn at a point (at_(1)^(2), 2at_(1)) of the parabola y^(2)=4ax meets on the point (ar_(2)^(2), 2at_(2)) then

If the normal to the parabola y^(2)=4x at P(1,2) meets the parabola again in Q then Q=

If the normals at points ' t_(1) " and ' t_(2) ' to the parabola y^(2)=4 a x meet on the parabola, then
