determine the lengths of the major and minor axes

An equation of an ellipse is given. 16x2- 64x + y2 + 2y + 1 =0 (a) Find the center, vertices, and foci of the ellipse. center (x, y) =( 2, - 1 focus (x, y) = ( 2, -1- 2V15 (smaller y-value) focus (x, y ) = ( 2, - 1 + 2V 15 (larger y-value) vertex (x, y) = ( 2, - 9 (smaller y-value) vertex (x, y) = ( (larger y-value) (b) Determine the lengths of the major and minor axes. major axis units minor axis units
