Introduction
In algebra, quadratic equations are a fundamental concept that can be expressed in various forms. One of the most important forms is the vertex form, which is represented as $y = (x - h)^2 + k$. This form provides valuable information about the graph of the quadratic function, including the vertex, axis of symmetry, and direction of opening. In this article, we will focus on converting the given quadratic equation $y = x^2 - 16x + 60$ into the vertex form.
Understanding the Vertex Form
The vertex form of a quadratic equation is a powerful tool for analyzing and graphing quadratic functions. It is represented as $y = (x - h)^2 + k$, where $(h, k)$ is the vertex of the parabola. The vertex form provides a clear and concise way to identify the vertex, axis of symmetry, and direction of opening of the parabola.
Completing the Square
To convert the given quadratic equation into the vertex form, we need to complete the square. This process involves manipulating the equation to create a perfect square trinomial. The general steps for completing the square are:
