I am kind of confused about X2; is it x^2 or 2x? Anyways just remind me if the way I did it is wrong.

Explanation:

I am only inferring that this is the question, so just remind me if I am wrong.

(x^2)/169+(y^2)/81=1

This is actually an equation for an ellipse, so just figure out the vertex of it and you will get the answer; or you can also use the graphing method. Another tip is that the center for this ellipse is (0,0), so we can use the a value to figure out the vertices, the solution to this problem.

The graph is a horizontal ellipse, since the larger a value is on the x^2 side. So now, all we have to do is add the a value to the center:(0,0).

So the answer is:
(-13,0); (13,0)
