Sketch Quadratic Graph
In this lesson, you will learn how to use the completing the square technique to rewrite any quadratic equation into a more useful form. We will first understand how the formula is derived, then go through three examples to help you apply it step by step.

Parts Of Quadratic Graph
In this video, you will learn about the different parts of a quadratic graph in the form \(y=ax^2+bx+c\), including the roots, the y-intercept, and the line of symmetry.
Sketch Quad Graph By Factorisation
In this video, we will learn how to sketch a quadratic graph using the factorisation method by first finding the roots, then identifying the y-intercept and axis of symmetry, and finally using these key points to draw an accurate curve.
Sketch Quad Graph By Complete The Sq
In this video, we will apply the completing the square formula and use the results to sketch a quadratic graph. You will learn how to identify key features such as the vertex, axis of symmetry, and direction of the curve to sketch the graph. Unlike the factorisation method, this technique allows us to sketch any quadratic graph, even when it cannot be easily factorised.
