Henry throws a tennis ball over his house. The ball is 6 feet above the ground when he lets it go. The quadratic function that models the height, in feet, of the ball after t seconds is h = -16t^2 + 46t + 6. Using the quadratic formula to solve, at what time does the ball hit the ground?

Pleas show all work and not just the answer please.
