Be careful where you put the 2 and 1 as one of these will be multiplied by three to give the middle term. Outsides and insides combine to give the middle. Completing the Square An example of the form ax2+bx+c is known as a quadratic. We can change this into a square term + a constant: (x±a)2±b This can be useful later when we move on to drawing quadratics and identifying maximum and minimum values. Method
