The value of x is
or 
Step-by-step explanation:
The expression is 
To complete the square, the equation is of the form 
The constant term c can be determined using, 

Rewriting the expression
and factoring the trinomial, we have,

Taking square root on both sides, we get,

Either,
or 
Thus, the value of x is
or 
We have been given the function 
Convert this expression in difference of cubes form.

Now, in order to find the factors, we can apply the difference of cubes form, which is given by

On applying this formula, we get

Hence, the factors of the given expression are

Out of the given option, A is the correct option.
x^5 − 4 is the required factor.
