See explanation.

#### Explanation:

First you can notice that

To check if the second expression can be factorized we have to calculate its discriminant:

The expression is:

the discriminant is:

The discriminant is greater than zero, so the equation has 2 distinct real roots:

and

So the complete factorization is:
