What is a Quadratic Equation? 🧐
A **quadratic equation** is any equation that can be written in the form $ax^2 + bx + c = 0$, where a, b, and c are numbers, and a is not zero. The solutions to these equations are called roots.
The tutorial will cover the three main methods for finding these roots: **factoring**, the **quadratic formula**, and **completing the square**.
