⚙️ Installation & Setup

Follow these steps to set up the quadratic solver locally:

# 1. Clone this repository to your local machine
git clone https://github.com/hatixntsoa/quadratic.solver.git

# 2. Navigate to the project directory
cd quadratic.solver

# 3. Give execute permission to the script
chmod +x quadratic.sh

# 4. Run the server to start the application
./quadratic.sh

✅ PHP must be installed on your system to run the server.

📌 Requirements

• PHP version 7.x or higher
• A Unix-like environment (Linux/macOS or WSL on Windows)

🚀 How It Works

The app solves quadratic equations of the form:

$$ ax^2 + bx + c = 0 $$

It uses the standard quadratic formula:

$$ x = \frac{-b \pm \sqrt{b^2 - 4ac}}{2a} $$

• If the discriminant ($△ = b^2 - 4ac$) is positive, two real roots are displayed.
• If the discriminant is zero, only one real root is shown.
• If the discriminant is negative, the app will return No Solution in R (from now on).
