Use completing the square to change the function into something like:
9(x - a)^2 + (y - b)^2 = c
Can you first figure out where the center of the ellipse is?
Hello, Joker37!
I bet that the "112" should be negative . . . even then, the answer is ugly!

Hi everybody!
I'm still stuck with this problem and unfortunately I have no-body to help me. I feel so alone.
Anyway, if it's because the question doesn't make sense or something like that please tell me and I will skip this question but I just don't like knowing that I don't know how to do something.
If you look carefully at the equations used, you will notice that and are different equations.
If you expand and simplify the simplified one, you will get: which I'm guessing is the equation you are trying to graph and that the one in the first post has a typing error?
Now that Soroban has supplied you with a method, why don't you give it a try yourself?
