1.	Let AB be a focal chord (not the latus rectum) of the parabola y2=4px where p is a prime number(p>0), such that the lengths, SA and SB are integers(S being the focus of the parabola). If the tangents to the parabola at A and B meet at point P, then
Answer» Let $A B$ be a focal chord (not the latus rectum) of the parabola $y^{2} = 4 p x$ where $p$ is a prime number $(p > 0),$ such that the lengths, $S A$ and $S B$ are integers( $S$ being the focus of the parabola). If the tangents to the parabola at $A$ and $B$ meet at point $P,$ then
