Quadratic equations and completing the square
my granddaughter who was revising for GCSE Maths asked me about “completing the squares” in algebra used for solving quadratic equations and I could not recall the technique. Later after a bit of googling I realised that it was the method used to determine the classic quadratic equation
The document below expands upon this, showing the “completing the squares” technique, a couple of examples and finally derivation of the quadratic equation. You can also download pdf by clicking on button
