15.4 Solving quadratic equations graphically

The quadratic equation ax^2+bx+c=0 is said to have no real roots if its graph does not cross the x-axis . If its graph just touches the x-axis, the equation has one repeated root. In this section, we learn about Introduction to Sketching Quadratic Equations, Sketch the Quadratic Equation and Find the Coordinates of Turning Point, 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:
