# 15.3 Graphs of Quadratic Equations

A quadratic function is a polynomial function with one or more variables in which the highest exponent of the variable is two. The graph of the quadratic function is called parabola. In this section, we learn about Solve Quadratic Equation by Factorising, Completing the Square, plot 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:
