The asymptotes y=2x and y=-2x tell us that the center of the hyperbola is (0,0).

With the foci in the x direction from the center (0,0), the equation is

The slopes of the asymptotes 2 and -2 tell us that b=2a; so the equation is

The distance from the center to each focus, c, is 15; c is related to a and b by

The equation is
