We know that the **algebraic identities of second degree** are

These identities can be used to factorise **quadratic polynomials**.

A **polynomial** is said to be **cubic polynomial** if its **degree is three**

The **algebraic identities** used in factorising a **third degree polynomial** are:

**Cubic polynomials** can be factorised using **Factor theorem**

**Factor theorem**: is a **polynomial **and is a real number, if, then is a factor of.
