What is focal Chord and If the chord joining P(a(t_(1))^(2);2at_(1)) and Q(at_(2)^(2);2at_(2)) is the focal chord ; then t_(1)t_(2)=-1

If the chord joining t_(1) and t_(2) on the parabola y^(2) = 4ax is a focal chord then

If the chord joining t_(1) and t_(2) on the parabola y^(2) = 4ax is a focal chord then

If the line joining the points (at_1^2,2at_1)(at_2^2, 2at_2) is parallel to y=x then t_1+t_2=
