Q. What is the center of the ellipse x2+36y2−72=0?Write your answer in simplified, rationalized form.(______,______)
Divide by 72: Divide the entire equation by 72 to get the standard form of the ellipse equation.72x2+7236y2=727272x2+2y2=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. Here, h and k are both 0, so the center is at (0,0).
