Q. What is the center of the ellipse 12x2+7y2−84=0?Write your answer in simplified, rationalized form.(______,______)
Divide by 84: Now, divide the entire equation by 84 to get the standard form of the ellipse equation.(8412x2)+(847y2)=8484
Simplify fractions: Simplify the fractions. 7x2+12y2=1
Identify center: Identify the center of the ellipse by comparing it to the standard form (x−h)2/a2+(y−k)2/b2=1. The center (h,k) is at (0,0) since there are no terms to shift the ellipse left/right or up/down.
