About quadratic equations and functions notes
GoConqr OriginalQuadratic equations and functions notes
The notes on this page cover both the shape of quadratic graphs and ways to solve equations. Quadratic Functions is a place to start with functions. The introductory notes on quadratic functions also introduce parabolas and vertices.
For methods, Quadratics Y1 brings together completing the square, the quadratic formula and sketching. The notes on solving quadratics by factorisation include an example, while Solving Quadratic Equations by Factoring offers another resource on that method.
Revise with notes
Read a section, then try the method yourself without looking at the notes. Return to the explanation if you get stuck. For graph work, use a note to review terms such as vertex and roots, then check how they appear on a parabola.
When you want to check your understanding with questions, switch to a quiz on the unit page. Try a note first, then use a quiz to check what you remember.
Frequently asked questions
Which note should I start with?
Start with the introductory notes on quadratic functions if you want to review parabolas and vertices. If you are revising several methods, Quadratics Y1 brings together completing the square, the quadratic formula and sketching. You can then choose a more focused note for the method you want to practise.
What do these notes cover?
The collection includes notes on quadratic functions and their graphs, as well as solving equations. Topics include factorisation, completing the square, the quadratic formula and discriminants. Some notes group several ideas together, while others focus on a single method, so you can choose according to what you are revising.
Are the notes free to use?
Yes. Every resource listed here is free to open and study without an account. The notes were made by GoConqr users, so their styles may differ. A free account also lets you make your own notes, quizzes, mind maps and flashcards, and save your quiz scores.
