Write an equation of an ellipse in standard form with center at the origin and with the given characteristics. (In this problem, think of "width" and "height" as the horizontal and vertical dimensions of the ellipse, respectively.)

a=2√7
b=3√2
width 6√2

How is working backward similar to solving an equation?
