This item is taken from IGCSE Mathematics (0580) Paper 41 of October/November 2014.
To deal with this item, let us summarize the details of the problem:
(a) Syllabus area: Algebra
(b) Specific topic: Quadratic Equations
Our goal is to make the left side of the equation to be of the form (x - p)^2 - q. We cannot use factoring for this quadratic since it is not a perfect square trinomial.
Let us then use completing the square:
