9x^2+4y^2+54x+8y-59=0 an ellipse in that needs to be in standard form explain how to do

D

edge

Step-by-step explanation:

The standard form of an ellipse is

Let's try to complete some squares: if we focus on the part involing x, we have

Similarly, for the part involving y, we have

So, the equation becomes

Divide both sides by 144 to get

which is the standard form
