It is known that the symmetry axes of the points (3, - 1) where the equiaxed hyperbola passes through are all on the coordinate axis, then the standard equation of the hyperbola is

It is known that the symmetry axes of the points (3, - 1) where the equiaxed hyperbola passes through are all on the coordinate axis, then the standard equation of the hyperbola is

The hyperbolic equation can be set as X & # 178 / A & # 178; - Y & # 178 / B & # 178; = ± 1 (a, B are all greater than 0)
Let a be a = B, and substitute a (3, - 1) into it. Let a be a & # 178; = 8
So the equation is X & # 178; - Y & # 178; = 8
