In this lesson I show you an algebraic method for completing the square. It's particularly helpful for those 'EXPRESS' the quadratic in completed square form type of questions. Question 1 is from Cambridge AS Pure Maths 1 9709/12/M/J/21 and question 2 05:15 is from Cambridge AS Pure Maths 1 9709/12/F/M/22.
