Answer:
f(x)=x-2
Step-by-step explanation:
You just have to change 5a for x
If
then complex number
is a root of cubic polynomial.
If polynomial has real coefficients, then conjugated
is also a root of polynomial.
Then the polynomial will be of a form

Since
then

Therefore,

(4x^4-1)÷x+1
(256x-1)÷x+1
256-1+1
256
The first step shows the problem
The second step powers 4x 4 times
The third step removes x
The 4th step shows the problem after x is removed.
The 5th step is the answer: 256
