x^2 - y^2 = 16 can be rewritten as x^2/4^2 - y^2/4^2 = 1

therefore, the conic section for x^2 - y^2 = 16 is Hyperbola.

therefore, the conic section for x^2 - y^2 = 16 is Hyperbola.

9x^2 + 4y^2 = 36 dividing 36 on both sides we get:

x^2/2^2 + y^2/3^2 = 1.

Therefore, the conic section for 9x^2 + 4y^2 = 36 is Ellipse.

x^2/2^2 + y^2/3^2 = 1.

Therefore, the conic section for 9x^2 + 4y^2 = 36 is Ellipse.
