Q. What is the center of the ellipse x2+3y2−9=0?Write your answer in simplified, rationalized form.(______,______)
Isolate variables: Now, we need to get the equation in standard form for an ellipse.Divide both sides by 9 to isolate the variables.9x2+93y2=99
Simplify the equation: Simplify the equation. 9x2+3y2=1
Identify center: Identify the center of the ellipse.The standard form of an ellipse is (x−h)2/a2+(y−k)2/b2=1, where (h,k) is the center.Here, the equation is already in standard form with h=0 and k=0.So, the center is (0,0).
