Answer:
is the required factorization of f(x).
Step-by-step explanation:
To factor the expression we must first group the terms and then take out common from these groups

Taking
common from first group and the 16 from second group we get:

Now, to factor in complex from we have to break term 

As, 
Also using identity 
On solving

is the required factorization of f(x).
