The vertices are
and foci are
.
Observe vertices and foci,
-coordinates are equal.
So, the hyperbola has a vertical transverse axis and its standard form is
.
Where,
is the center.
is the distance between center and vertex.
is the distance between center and focus.
.
By the midpoint formula, the center of the hyperbola is
.
The distance between center and vertex is
.
The distance between center and focus is
.

Substitute the values of
and
in standard form of the hyperbola.

The standard form of the hyperbola
.
