Q. What is the center of the ellipse x2+9y2−18=0?Write your answer in simplified, rationalized form.(______,______)
Isolate terms with x and y: Now, we need to get the equation in standard form for an ellipse.Divide both sides by 18 to isolate the terms with x and y.18x2+189y2=1818
Simplify the equation: Simplify the equation further. 18x2+2y2=1
Identify the 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, we have (x−0)2/18+(y−0)2/2=1, so the center is (0,0).
