## (1) A circle is concentric with the ellipse  (x^2)/(a^2) + (y^2)/(b^2) =1 and passed through the focus F1 and F2 of the ellipse.  Two curves intersect at four points. Let  P  be any point of intersection. If the major axis of the ellipse is  15  and the area of the triangle PF1F2  = 26 , then find the value of 4a^2  - 4b^2 .
