A **quadratic equation **or **second degree equation **in is written in standard form as

with

If , then quadratic equation reduces to linear equation, i.e., .

The word **Quadratic **is derived from Latin word **Quadratum **which means “related to two or to make square”.** **

__Examples__:

__Solution of Quadratic Equations__:

The process of finding the values of unknown quantity (variables) which satisfy the given quadratic equation is called solution of quadratic equation. The values which satisfy the quadratic equation are called the roots of the quadratic equation. A set consisting of all roots of the quadratic equation is called solution set.

We discuss three methods for solving quadratic equations: **factorization**, **completing the square** and using the **quadratic formula**. In the next tutorials we explain all the three methods for solving quadratic equation.
