Finding Roots of Quadratic Equation

# Introduction

A quadratic equation is an equation of the form `ax²+bx+c=0`, where `a`, `b`, and `c` are constants. In this lab, we will learn how to write a program to find the roots of a quadratic equation.

To solve the quadratic equation, we will use the following formula:

`x = (-b ± sqrt(b² - 4ac)) / 2a`

> Note: You need to create the file `~/project/main.c` yourself to practice coding and learn how to compile and run it using gcc.

cd ~/project
# create main.c
touch main.c
# compile main.c
gcc main.c -o main
# run main
./main
