The equation of parabola is
and the point is
.
Slope of the tangent is derivative of the curve.
\
Apply derivative on each side with respect to
.

Slope of the tangent is
.
Point-slope form of line equation :
.
Substitute
and
in the above formula.

This is a pair of tangent lines.
\These tangent lines intersect the parabola, and the intersecting points can be determined by solving them.
\Substitute
in the curve
.

and
.
Substitute
values in
.
If
, then
.
If
, then
.
Therefore, the points at tangent lines intersect parabola are
and
.
