The completing the square method was used in this maths tutorial to factorise a quadratic function. To complete the square, the coefficient of x^2 must be equal to 1. Questions that were answered in this maths tutorial are what are the steps in completing the square, howtocompletethesquare, and how do I complete the square.

Quadratic expressions are written in the form ax^2+bx+c. Quadratic expressions are factorised by completing the square, using the difference of two squares. using the quadratic formula or factorising by inspection. Inorder to complete the square, make sure that the coefficients of x^2 is one. The quadratic expression in the example was factorised so that the coefficient of x was one. The coefficient of x in the quadratic expression was halved and squared. it was then added and subtracted in the quadratic expression. Thereafter, the quadratic expression was factorised by completing the square. The result (y=a(x+p)^2+p is very useful when identifying the y-intercepts and the turning point or stationery points of the quadratic function on a graph.
