## Understanding Quadratic Equations

Quadratic equations are polynomial equations of the form `ax^2 + bx + c = 0`

, where `x`

is the variable, and `a`

, `b`

, and `c`

are constants. These equations frequently appear in various mathematical problems and are characterized by their quadratic degree (`x^2`

term).

## The Importance of Completing the Square

Completing the square is a mathematical technique used to rewrite a quadratic equation in the form `(x - h)^2 = k`

, where `h`

and `k`

are constants. This form is particularly useful for analyzing the properties of the quadratic equation and finding its solutions.

## Introducing the Completing the Square Calculator

The Completing the Square Calculator is a user-friendly tool designed to automate the process of completing the square for quadratic equations. By entering the coefficients `a`

, `b`

, and `c`

of the quadratic equation, the calculator efficiently provides the completed square form and the solutions.

## How Does the Calculator Work?

The Completing the Square Calculator employs mathematical formulas to complete the square for quadratic equations:

```
Step 1: Calculate the Discriminant (D) = b^2 - 4ac
Step 2: If D < 0, the equation has no real roots (imaginary roots).
Step 3: If D = 0, the equation has one real root (perfect square).
Step 4: If D > 0, the equation has two real roots.
Step 5: Calculate the x-coordinate of the vertex (h) = -b / 2a.
Step 6: Calculate the y-coordinate of the vertex (k) = f(h) = ah^2 + bh + c.
Step 7: Write the equation in completed square form: (x - h)^2 = k.
Step 8: Calculate the solutions if applicable.
```
