Normal at `P(at_1^2,2at_1)` meets the curve again at point `Q(at_2^2, 2at_2)` then `t_2=-t_1-2/t_1`

The normal drawn at a point (at_(1)^(2),-2at_(1)) of the parabola y^(2)=4ax meets it again in the point (at_(2)^(2),2at_(2)), then t_(2)=t_(1)+(2)/(t_(1))(b)t_(2)=t_(1)-(2)/(t_(1))t_(2)=-t_(1)+(2)/(t_(1))(d)t_(2)=-t_(1)-(2)/(t_(1))

The normal at (a,2a) on y^(2)=4ax meets the curve again at (at^(2),2at). Then the value of t=

The normal to the rectangular hyperbola xy=4 at the point t_(1), meets the curve again at the point t_(2) Then the value of t_(1)^(2)t_(2) is

If the normal to the rectangular hyperbola xy = 4 at the point (2t, (2)/(t_(1))) meets the curve again at (2t_(2), (2)/(t_(2))) , then

If the normal at(1, 2) on the parabola y^(2)=4x meets the parabola again at the point (t^(2), 2t) then the value of t, is
