This is an abbreviated response without all the steps.

Complete the squares for the x and the y and put into standard form.

You need to factorize first for the x terms and for the y terms; and inside parentheses, you need 4 for the x's and 1 for the y's.

4%28x%2B2%29%5E2%2B9%28y-1%29%5E2=36

You finish this ellipse equation to standard form.
