# (x+1)(x−1)(x+2)(x+4)

#### Explanation:

First thing to always remember is a bi quadratic has 4 roots whether they are distinct or not.

Start of with the basic

We find that

Lets divide

Now factor

Now

We have found the four roots and hence we can be certain we have factored the given polynomial completely
