Q. What is the center of the ellipse x2+15y2−90=0?Write your answer in simplified, rationalized form.(______,______)
Divide by 90: Divide the entire equation by 90 to get the standard form of the ellipse equation.90x2+9015y2=909090x2+6y2=1
Identify center: Identify the center of the ellipse by comparing the equation to the standard form (x−h)2/a2+(y−k)2/b2=1. Since there are no (h,k) terms, the center is at (0,0).
