Step 1:

\

The foci of ellipse are \"\".

\

The length of major axis is \"\".

\

\"\"

\

The center is midpoint of foci \"\".

\

center is \"\".

\

The distance from the center to one of the  foci is \"\".

\

The distance between \"\" and \"\" is,

\

\"\"

\

In ellipse \"\".

\

Substitute \"\" and \"\" in \"\".

\

\"\"

\

The standard form of a ellipse is \"\".

\

Substitute \"\" in standard form of ellipse.

\

\"\"

\

\"\"

\

Solution :

\

The ellipse equation is \"\".
