You have worked with polynomial expressions so far, but you have not yet worked with polynomial equations. We will now focus on polynomial equations that are of degree 3 or higher. The process for solving these polynomial equations is not all that different than the processes used for solving quadratic equations. Your goal in solving these types of problems is actually to simplify the polynomial equation to quadratic and/or linear parts. You will often do this by factoring. As a review, briefly explain the process to check that the solution you found is correct
