Lesson Summary:
In this lesson, we learn how to factor simple quadratics. These quadratics have only one variable and the highest power is two. Using a reverse foil method, we can find the two numbers that multiply to give the last number and add to give the number in front of the variable. We then place these two numbers in the parentheses with the variable and we have factored the quadratic.
