Q. What is the center of the ellipse 6x2+13y2−78=0?Write your answer in simplified, rationalized form.(______,______)
Divide by 78: Divide the entire equation by 78 to get the coefficients of x2 and y2 to be 1. (78/6)x2+(78/13)y2=7878Simplify the fractions.13x2+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. The center (h,k) is at the origin (0,0) since there are no terms to shift the ellipse left/right or up/down.
