As a follow-up to my last post, Simplifying Radical Expressions, this instructional piece transitions to quadratic equations in which simplifying radicals is necessary. Solving quadratic equations is the precursor to graphing quadratic equations and studying the nature of parabolas. This unit hinges on students bringing all of their knowledge of solving equations and factoring, while also acting as a springboard to understanding everything there is to know about parabolas.
The instructional piece below is intended to help you teach your students to solve quadratic equations. Inside the Word document are links to previously posted material that you may find helpful. The pdf version is there in case you’re unable to open the Word file. As always, I look forward to your comments, questions and suggestions. I also encourage you to post instructional strategies you have found successful in your classroom.
