Hello, soly_sol!

You're still making silly mistakes . . .

The center is: .Graph the ellipse: .

I got:

. . . No!

I divided all the terms by 36: . . . . . No!

If this is true, you need more help than we can give here.This is where I am stuck at and dont know what to do next or how to graph it.

I divided all the terms by 64: . . . . . Stop doing that!

I assume you meant: .Find the foci of the ellipse: .

I got: foci at (-3, +squareroot 11, 3) and (-3, -squareroot 11, 3)

. . . . . This doesn't make sense
