The equation [tex]Ax^2 + By^2 + Cx = 1 [/tex] represents an ellipse. If [tex]A > 0[/tex] and [tex]B > 0[/tex], what conditions must be satisfied if the ellipse has it's major axis on the y-axis?(adsbygoogle = window.adsbygoogle || []).push({});

The answer is "[tex] C = 0[/tex] and [tex]A > B[/tex]"

When I first wrote this question I thought [tex]A > B[/tex] should have been [tex]A < B[/tex]. So how do I figure out what the restrictions are? Why is [tex]A < B[/tex] wrong?
