If three normals drawn to any parabola `y^2=4ax` from a given point `(h,k)` are real then `h>2a`

Three normals drawn to the parabola y^(2) = 4x from the point (c, 0) are real and diferent if

The algebraic sum of the ordinates of the feet of 3 normals drawn to the parabola y^2=4ax from a given point is 0.

Three normals are drawn to the parabola y^(2) = 4x from the point (c,0). These normals are real and distinct when

The algebraic sum of the ordinates of the feet of 3 normals drawn to the parabola y^(2)=4ax from a given point is 0.
