1, the standard equation of hyperbola 7x ^ 2 - 2Y ^ 2 + 8 = 0 is - the coordinate of intersection is—— 2. Ask for the hyperbolic standard equation of points F1 (0. - 5), F2 (0.5) and passing through point a (0.3)—— 3. On the hyperbola 4x ^ 2 - y ^ 2 + 64 = 0, the distance from a point P to one of its focal points is equal to 1. Then the distance from point P to another focal point is equal to 1———— I have run out of marks. I have no choice

1. Y ^ 2 / 4-x ^ 2 / (8 / 7) = 1 (0,6 radical 6 / 7), (0, - 6 radical 6 / 7)
2. C = 5, a = 3, then B = 4, y ^ 2 / 9-x ^ 2 / 16 = 1
3. The standard equation, a = 8,17
