Complete the square to find the vertex and axis of symmetry

The video tutorial explains the process of completing the square for quadratic equations. It begins by discussing the conditions under which completing the square is applicable, specifically when the coefficient of the quadratic term is 1. The tutorial then guides through the steps of creating a perfect square trinomial by factoring and adjusting terms. It further explains how to factor the trinomial into a binomial squared and simplifies the expression. Finally, the video demonstrates how to find the vertex and axis of symmetry of the quadratic equation.
