In this lesson, you learn how to solve rational equations by multiplying until you get rid of the denominators. By using this method, we can get to the answer faster than using other methods like factoring or graphing. However, we still need to use older methods to solve the equation once it is no longer rational. To get more accurate answers, using the quadratic formula may be required instead of just relying on the calculator.
