Lesson Summary:
In this lesson, you will learn how to solve quadratic equations by factoring and using the zero product property. The zero product property states that if two numbers multiplied together equal zero, then one of the numbers must be zero. By factoring the quadratic equation, you can set each factor equal to zero and solve for the variable, which gives you the solutions to the equation. It's important to check your solutions by plugging them back into the original equation to make sure they work.
Lesson Description:
Covers zero-product property and part 1 of how to solve non-linear equations by factoring.
