Best ResponseYou've already chosen the best response.1try taking it this way: \(x^2 + 16y^2  96y + 128 = 0\) \(x^2 + 16(y^2  6y) + 128 = 0\) \(x^2 + 16[(y 3)^2 9] + 128 = 0\) etc etc ......until you have it in the standard form, which here is: \( \displaystyle{\left(\frac{x}{a}\right)^2 + \left(\frac{y  y_o}{b}\right)^2} = 1\) there's no point asking computers to do it for you :p
