Taking the general equation of hyperbola and comparing with
we get that
and
Eccentricity(e) of the hyperbola will be
e=
we get e=
foci will be (+/- ae,0)
which are
(+/- 11
vertices are(+/- a,0)
which are(11,0)
as the rhs=1 the hyperbola will be towards +ve and -ve x axis with its axis as the x and y axis.
