You can put this solution on YOUR website!
Given: 4x%5E2%2B9y%5E2=36
%284x%5E2%29%2F36%2B%289y%5E2%29%2F36=36%2F36
%28x%5E2%29%2F9%2B%28y%5E2%29%2F4=1

Knowledge about the values in the equation of an ellipse gives a=3, b=2, and this means that, since the ellipse is in standard position, vertices are (0,-3), (0,3), (-2,0), (2,0). The center is the origin.
