Welcome to the page on quadratic equations.  On this page you’ll find all you need, from the most basic and fundamental concepts and procedures, right up to the most complicated applications involving quadratic equations.

The concepts and skills required for mastery are organized in a specific fashion, as shown in the links below.  You can use an individual page as a refresher, but it might be good to work through the entire sequence.  Read through the notes, watch the videos, try the practice problems.  Give it a shot and see how you do.  And please, don’t be bashful about reaching out for help.  Leave a comment at the bottom of the page, or in one of the videos.  I’d love to hear from you.
