Quadratic form and graphs

A quadratic expression has the form ax2+bx+cax^2+bx+cax2+bx+c, where aaa, bbb, and ccc are constants and a≠0a\neq0a=0. A quadratic equation is formed by setting this equal to zero, usually as ax2+bx+c=0ax^2+bx+c=0ax2+bx+c=0.

Step-by-step lessons covering Edexcel AS Level Maths Quadratics for AS Level Maths. Each lesson breaks down 2.1 Solving Quadratics, 2.2 Completing the Square, 2.3 Sketching Quadratic Graphs, 2.4 The Discriminant, and 2.5 Modelling with Quadratics, then works through exam-style questions in Paper 1 and Paper 2 format. Build fluency in the core algebra, surds and trigonometry topics early, since they underpin the calculus, statistics and mechanics content that follows.
