How to use zero product property to solve a quadratic in factored form

The video tutorial explains the zero product property, demonstrating how to solve equations where the product of terms equals zero. It walks through solving the equation step-by-step, verifying solutions by substituting values back into the original equation, and introduces the concept of solution sets, including their notation and usage in tests.

Explain how plugging in values for X can verify the solutions.
