Chapter 9 Equations and Inequalities

# 9.1 Solving Quadratic Equations 1

A quadratic function is a function of the form f(x) = ã€–axã€—^2 + bx + c, where a, b and c are real numbers with a â‰ 0. A quadratic function is a function of the form f(x) = ã€–axã€—^2 + bx + c, where a, b and c are real numbers with a â‰ 0. In this section, you learn about Solving Quadratic Equations, quadratic equations, Solving Quadratic Equations by Factorising, solve quadratic equations.

If you're a student in a school/college that's based in England, you might be entitled for full access to our eLearning platform where you can access to all our tutorial videos and practice questions.

Please check with the head of Maths or deputy headteacher at your school/college to request access if they've already registered to our free pilot subscription. They can always reach us at the below email:
