A quadratic equation is any equation with the general structure of:where a ≠ 0. The name “quadratic coefficient” is given to the values of a,b & c. Quadratic equations are a major topic of secondary school algebra and they remain important when doing higher mathematical studies.
Depending on the type of quadratic equation and if it can be factorised, we can apply the following techniques to solve it.•Factorisation•Competing the Square•Solve using Quadratic Formula•Solving graphicallyWe will teach you how to use almost all of these techniques to find the solution to any quadratic equation.
Quadratics can also represent parabolas on graphs. We can solve quadratics and then sketch them to get a similar result as you can see on the right.
It*s time that you start working with quadratics. We recommend that you try solving quadratics using factorisation before moving on to any of the other methods as it is the easiest. Please share this page if you like it or found it helpful!
