Completing The Square Calculator


About Completing The Square Calculator (Formula)

A Completing The Square Calculator is a mathematical tool used to convert a quadratic equation from standard form (ax^2 + bx + c = 0) to vertex form (a(x – h)^2 + k = 0), making it easier to analyze and solve. This technique is fundamental in algebra and is often used to find the solutions of quadratic equations. The formula for completing the square involves manipulating the equation to isolate the squared term and constant term.

The formula for completing the square for a quadratic equation ax^2 + bx + c = 0 is:

ax^2 + bx + c = a(x – h)^2 + k


  • a, b, c are coefficients of the quadratic equation.
  • h, k are constants that represent the coordinates of the vertex of the parabola.

Using the Completing The Square Calculator involves these steps:

  1. Input: Enter the coefficients of the quadratic equation (a, b, c) into the calculator.
  2. Calculation: The calculator completes the square by manipulating the equation to vertex form and determines the values of h and k.
  3. Output: The calculator displays the quadratic equation in vertex form and provides the coordinates of the vertex.

This tool is particularly useful for students and mathematicians who want to solve quadratic equations, graph parabolas, and understand the properties of quadratic functions.

For example, if you have a quadratic equation 2x^2 – 4x – 6 = 0, the Completing The Square Calculator will convert it to vertex form and provide the coordinates of the vertex.

In the field of algebra, quadratic equations and their solutions play a fundamental role in various mathematical and scientific applications, making the Completing The Square Calculator a valuable tool for problem-solving.
