Set the function to equal zero:
To find the zeros, or solutions, to this problem, we will use the quadratic formula:
Plug the values into the equation:
Solve for both plus and minus:
The question cannot use a negative value for x, as the diver cannot dive a negative distance from the board.
The answer is '<span>x = 5; the diver hits the water 5 feet away horizontally from the board', because x represents the horizontal distance away from the board.</span>
