The foci are at
and
.
The eccentricity is
.
Since the
-coordinates of foci are same, the hyperbola has a horizontal transverse axis.
The standard form of hyperbola with horizontal transverse axis is
.
Where,
\
,
Center :
,
Vertices :
,
Foci :
,
Transverse axis :
,
Conjugate axis :
,
Eccentricity :
.
Asymptotes :
.
The center is the mid point of the foci.
\
.
The distance from a focus to the center is
units.
So,
.
Eccentricity :
\
Find the value of
by using the values of
and
.

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

.
The equation of hyperbola is
