To determine how far the soccer ball has traveled when it hits the ground, Leon correctly set the height \( h(x) \) equal to 0, resulting in the equation:
\[ 0 = -12x(x - 20) \]
To use the Zero Product Property, we recognize that for the product of two factors to equal zero, at least one of the factors must be equal to zero. This gives us two equations to solve:
- \( -12x = 0 \)
- \( x - 20 = 0 \)
Now, we can solve each equation:
-
From \( -12x = 0 \), we can divide both sides by -12: \[ x = 0 \]
-
From \( x - 20 = 0 \): \[ x = 20 \]
Thus, the horizontal distances where the height of the soccer ball equals 0 (where it hits the ground) are \( x = 0 \) and \( x = 20 \).
The correct response to the question is:
Solve the two equations: −12x=0 and x−20=0.
