Full solution stays hidden until you ask for it.
1. Group and factor coefficients of squared terms.
2. Complete the square inside each group.
3. Move constant and divide so right side is 1.
4. Read center and axis lengths.
Use the worked steps, then substitute the final answer back into the original relationship to confirm it satisfies the prompt.
Leaving right side not equal to 1 for standard ellipse form.
