The path of a soccer ball can be modeled by the equation h(x)=−12x(x−20) , where h(x) is the height of the ball, and x is the horizontal distance the ball has traveled. To determine how far the ball has traveled when it hits the ground, Leon set the height equal to 0 and obtained the equation: 0=−12x(x−20) . How can he use the Zero Product Property to find the horizontal distance the ball has traveled when the height of the soccer ball equals 0?(1 point)

Cancel out the x and then multiply −12 and −20.
Cancel out the x and then multiply negative Start Fraction 1 over 2 End Fraction and negative 20 .

He cannot use the Zero Product Property because the height will never be 0.

Plug in 0 for all the x terms in the function.

Solve the two equations: −12x=0 and x−20=0.

Answer 1

To find the horizontal distance the ball has traveled when the height is equal to 0 using the Zero Product Property, Leon should solve the equation:

\[ 0 = -12x(x - 20) \]

By the Zero Product Property, if the product of two factors is zero, at least one of the factors must be zero. Therefore, he can set each factor equal to zero:

1. \(-12x = 0\)
2. \(x - 20 = 0\)

Now, solving these equations:

1. For \(-12x = 0\): \[ x = 0 \]

2. For \(x - 20 = 0\): \[ x = 20 \]

Thus, the horizontal distances where the height is 0 are \(x = 0\) and \(x = 20\). This means the ball hits the ground at these two points (when it is kicked and when it lands).

Therefore, the correct response is:

Solve the two equations: −12x=0 and x−20=0.
