Solving Quadratic Equations by Factoring

What does the zero product property imply?

• If the product of two numbers is zero, at least one of the numbers must be zero.

• If the product of two numbers is zero, both numbers must be zero.

• The product of two numbers can never be zero.

• The zero product property is not applicable to quadratic equations.
