Quadratic Equation Solver

A simple tool that helps you solve mathematical Quadratic equations.

Overview

The challenge

Users should be able to:

• See the overal form of any Quadratic equation.
• Input the value of the three variables a, b, and c. Then, hit the 'Calculate' button to possibly get the root(s) of the Quadratic equation.
• Clear all inputs at any time by clicking on the 'clear inputs' button with the 'trash can' icon.

My process

Built with:

• Semantic HTML
• Tailwind CSS - Styling
• Vanilla JavaScript

I learned:

• How to extract key-value pairs of data from an HTML form using JavaScript.
• How to use math, mrow, mo, and other math-related HTML elements.
• Input validation with the pattern HTML attribute.

Development setup

1. First, you need to clone the project:

git clone https://github.com/ShayanTheNerd/quadratic-equation-solver.git

Alternatively, you can copy the source of the project directly to your local environment using Degit:

pnpm i -g degit

degit https://github.com/ShayanTheNerd/quadratic-equation-solver new-project-folder

2. Then, install required packages:

pnpm i

3. Finally, run the dev script to start the dev server:

pnpm run dev

Now, you can preview the project on a local server of your choice. My personal recommendation is the Live Server Extension.

Deployment and production

Before deploying the project or creating a new pull request, run the following commands and make sure there are no errors:

pnpm run format

pnpm run build
