<h3>How to factorize a polynomial?</h3>
Let the polynomial A(x) has one factor f(x).
Then, it means, we have:

Thus, A(x) can be written as 
Thus, the other factor of that polynomial is

For given case, the polynomial
is

Its one factor f(x) is given 
Thus, its second factor is obtained as:

Thus, the second factor of the given polynomial is
