It is easier and smarter to show that the co-ords of T satisfy the eqns of tangents at P and at Q. Usually much harder to do it by finding the co-ords of point of intersection of the two tangents(by solving for simultaneous eqns).

For example, for tangent at P:

For this particular question, finding point of intersection is not that much harder though.
