x

What is a quadratic?

Graph of the parabola y = x^2 - x - 6 crossing the x-axis at -2 and 3, with roots and vertex labelled A quadratic equation has highest power 2 and is usually written as $ax^2+bx+c=0$ , where $\neq 0$ . In this lesson, we focus on forms like $x^2+bx+c=0$ , where the coefficient of $x^2$ is 1 and factorising is usually the best method.

Solving Quadratics

Step-by-step lessons covering Oxford AQA IGCSE Maths Solving Quadratics for Core and Extended tier. Each lesson works through exam-style questions in Paper 1 and Paper 2 (Core: 1C and 2C; Extension: 1E and 2E) format. Since content from any part of the specification can appear on either paper, keep number and algebra fluency sharp throughout the course rather than leaving it until near the exam.
