Hyperbola 25 / x square - 9 / y square = 1 any point P is closer to this hyperbola, the distance from one focus is 2, find the distance from point P to another focus
According to the definition of hyperbola, the absolute value of the difference between the two focal points is 2A
In this problem, let the distance be x, then X-2 = 10, x = 12
So the distance is 12
