This resource has students solve 6 different quadratic equations using all four methods (factoring, square roots, completing the square, and the quadratic formula) for each of the six equations. This resource does a great job of showcasing to students that no matter which method is used, the solutions should be the same. This worksheet is a great final review activity for a unit on solving quadratics. It can also be used as a great way for students to discover that sometimes multiple methods could be used, but one method is faster/easier than the others.
