Hi,
vertices on the x-axis: (8,0)and (-8,0) Hyperbola opens right and left.
Standard Form of an Equation of an Hyperbola is %28x-h%29%5E2%2Fa%5E2+-+%28y-k%29%5E2%2Fb%5E2+=+1
where Pt(h,k) is a center with vertices 'a' units right and left of center
and asymptotes that pass thru the center with slope = ± b/a
In this example: center is (0,0) with a = 8
x^2/8^2 - y^2/b^2 = 1
foci (c,0) and (-c,0) are (sqrt(89), 0),-sqrt(89), 0 }}}
c, the distance from the center to the foci
c^ = a^2 + b^2
sqrt%2889%29%5E2 = 8^2 + b^2
89 = 64 + b^2
25 = b^2
b = ± 5
x^2/8^2 - y^2/5^2 = 1
x%5E2%2F64+-+y%5E2%2F25+=+1
