In this unit of work students will learn how many quadratic expressions can be factorised. There’s no sign up needed and you can check each answer (with explanations) as you go to make sure you’re on the right track. Maths Made Easy has a short online test which students can do at home or in class. Quadratic expressions are considerably more complicated to work with than linear expressions, and students often find them hard to handle. Use quadratic equations to bring together mathematical techniques.The first activity focuses on factorising quadratics where the coefficient of x^2 is 1, followed by a second where the coefficient is greater than 1. This is a two-part factorising quadratics lesson from PixiMaths. Once you’ve watched the videos head on over to where you’ll find worksheets of exam-style questions and textbook exercises for each one. This video from the ever reliable Corbettmaths is a good guide for students on factorising quadratics, and runs through some examples in a straightforward and easy-to-follow manner. This lesson plan from Colin Foster helps students become confident and fluent with techniques such as factorising quadratics by offering a scenario in which they need to construct their own quadratic equations in order to solve a bigger problem… Let students construct their own quadratic equations.
