The equation of the major axis of 25x^(2) + 16y^(2)-100x - 96y - 156 = 0 is

The eccentricity of the ellipse 25x^(2) + 16y^(2) - 150 x - 175 = 0 is

I. 12x^(2) + 82 x + 140 = 0 II. 16y^(2) + 48y+ 32 = 0

If the lengths of tangents drawn to the circles x^(2) + y^(2) - 8x + 40 = 0 5x^(2) + 5y^(2) - 25x + 80 = 0 x^(2) + y^(2) - 8x + 16y + 160 = 0 From the point P are equal, then P is equal to
