Quadratic Equations
On this page you will find several videos on solving quadratic equations. We look at solving quadratics first by factorising and then move on to looking at using the quadratic formula.
There is also a short video on difference of two squares.

In this second video on solving quadratic equations, we explore the method a bit deeper, and look at a couple of different situations that you might come across.

In this third video we look at how we must rearrange a quadratic before we can solve it.

|
In this fourth video we look at some algebraic fractions within equations that lead to quadratics to solve.
