This video tutorial focuses on the zero product property, explaining that if the product of two numbers is zero, then at least one of the numbers must be zero. This property is particularly useful in solving quadratic equations. The tutorial demonstrates how to apply the zero product property to factor and solve quadratic equations, providing practice problems for better understanding. The lesson concludes with a second example to reinforce the concept.

What is the zero product property?

• If the sum of two numbers is zero, one of them must be zero.

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

• If the quotient of two numbers is zero, one of them must be zero.

• If the difference of two numbers is zero, one of them must be zero.
