Question

Find the foci for the ellipse 9x^2 + 18root3x + 4y^2 - 16y +7= 0 and graph the curve showing all pertinent data including vertices, foci, major axis, and minor axis

Answer 1

18root(3x)? You mean like \[18\sqrt{3x}\]?

Answer 2

Yes (:

Answer 3

No. It should be \[18\sqrt{3}x\]

Answer 4

huh... that is weird. I don't know how you would complete the square with that term

Answer 5

I took the nine out and then divided the 2 root 3 by 2 and squared and got 3. I then got a wierd equation.
