Use the Zero Product Property
1. A child launches a toy rocket from the top of a slide at the
park. Suppose the equation 16t^2 + 28t + 8 = 0 can be
used to find how many seconds it will take for the rocket to
hit the ground.
a.
Write the equation in factored form
i.
4(t – 2)(4t + 1)
b. Use the zero-product property to solve the equation.
Show all the steps needed to find both answers.
c.
Explain how the solution relates to this situation.

2. A manufacturing company manufactures a cardboard box

with a square base and a height of 15 inches. Suppose the
equation x^2 + 60x – 7,200 = 0 can be used to find the
length and width of the base of the box, each measuring x
inches.
a.
Write the equation in factored form.
