Major axis is vertical based on "foci are (2, 3) and (2, -3)." The equation will be like this:
.

so meaning .

Again using foci are (2, 3) and (2, -3), .

You also see that the center of the ellipse from the focal information is at (2,0), so the equation can be seen as:
----------Almost done.

Are you aware that the relationship amoung a, b, and c, is ? Use this to find b and finish the equation.
