The path of a ball kicked from the ground can be modeled by the equation y=-1/5 (x-5) (x-20), where x and y are measured in feet. The x-axis represents the ground. How far does the ball land from where it is kicked?

Step-by-step explanation:

This is already factored for the zeros of the quadratic. If x - 5 = 0 and x - 20 = 0 then x = 5 and 20. The ball was kicked 5 feet out and landed at 20 feet down the field. The difference is 15 feet. That's how far the ball traveled from its initial position on the ground to its landing place.

So 15 feet from where it was kicked.
