GCSE Maths - How to Factorise Quadratics by Completing the Square (Part 1 - Factorise When a=1) #52

The video tutorial explains the method of completing the square to solve quadratic equations. It begins with an introduction to the technique, followed by a detailed walkthrough of two examples. The first example involves rearranging the quadratic equation X^2 - 10X + 18 into the form X + P^2 + Q, where P and Q are constants. The second example uses a similar approach with the equation X^2 + 6X + 8, demonstrating the method's consistency. The tutorial emphasizes practice and understanding of the steps involved.
