Question #252eb

Answer 1

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)`
