The correct answer is: 6, 52

Since, the vertex of the hyperbola are A-2, 0 and A2, 0.

Hence, the transverse axis of the hyperbola is x- axis and centre is O0,0.

Equation of hyperbola can be taken as

x2a2-y2b2=1

a=2 and ae=3

e=32

Since, b2=a2e2-1b2=a2e2-a2=9-4=5

Hence, equation of hyperbola is x24-y25=1

Clearly, point 6, 52 doesn't lies on the hyperbola.
