If the line 5x-4y-12=0 meets the parabola x^(2)-8y in A and B then the point of intersection of the two tangents at A and B is

The line y=x-2 cuts the parabola y^(2)=8x in the points A and B. The normals drawn to the parabola at A and B intersect at G. A line passing through G intersects the parabola at right angles at the point C,and the tangents at A and B intersect at point T.

Consider the parabolas y^2=4x , x^2=4y Find the point of intersection of the two parabolas.
