## Homework Statement

6x2 + 8y2 + 32y - 16 = 0

## Homework Equations

## The Attempt at a Solution

I think I made a mistake.

This is how far I got

4(x-4)^+3(y+9)^=120

I made a mistake. Can someone delete this thread?

What did I do wrong?

I can't tell what you did wrong since you didn't show your work, but the equation you ended with isn't right.

6x

<==> 6x

Now complete the square in the y terms so that the equation becomes

[tex]\frac{x^2}{a^2} + \frac{(y - k)^2}{b^2} = 1[/tex]

Since there is no first-degree x term in the original equation, don't try to complete the square in the x terms.
