To find the horizontal distance the ball has traveled when the height is 0, Leon can apply the Zero Product Property to the equation \( 0 = -12x(x - 20) \).
Using the Zero Product Property, we set each factor equal to zero:
- \(-12x = 0\)
- \(x - 20 = 0\)
From the first equation, \(-12x = 0\) gives: \[ x = 0 \]
From the second equation, \(x - 20 = 0\) gives: \[ x = 20 \]
Thus, the two solutions for \(x\) are \(0\) and \(20\). This means the ball hits the ground when it has traveled \(0\) units (at the moment it is kicked) and \(20\) units (when it lands).
Therefore, the correct response for Leon is: Solve the two equations: −12x=0 and x−20=0.
