The ellicpse $\"\"$ is symmetric with respect to the origin.

Explanation :

If $\"\"$ is a point on the ellipse,then $\"\"$ must also be on the ellipse.

This can be determined because the $\"\"$ and $\"\"$ terms are squared.

$\"\"$

Thus, $\"\"$ is also a point on the ellipse and the ellipse is symmetric with respect to the origin.
