The Quadratic Formula - Defintion & Examples

A baseball player hits a baseball that lands $x$ feet away from home plate, where $x$ is the larger of the two roots of $$-2x^{2}+1040x-38400=0.$$ If a standard baseball field is $400$ feet from home plate to the center field wall and $450$ feet from home plate to the edge of the stadium, is this player's hit a home run? Does it exit the stadium? Use the quadratic formula to solve.
