The eccentricity of the  parabola y² – 2x – 6y + 5 = 0 is

The ordinate of  the centroid of the triangle formed by conormal points on the parabola y²=4ax is

If z² = (x^1/2 + y^1/2)/(x^1/3 + y^1/3), then x(∂z/∂x) + y(∂z/∂y) is :

AB,AC are tangents to a parabola y²= 4ax. If l₁,l₂,l₃ are the lengths of perpendiculars from A,B,C on any tangent to the parabola,then

the equation of the parabola whose vertex is (3,-2) axis is parelle to x- axis and latus rectum 4 is

The equation to the pair of tangents drawn from (3,-2) to the parabola y² = x  is
