Answer:
2x-3
Step-by-step explanation:
You use polynomial division to solve this, I tried to write down a little bit of my thinking process but I cant write everything out
Use the difference of squares factorization - that for any numbers a and b, (a-b)(a+b)=a^2-b^2.
We have:
(x^2+1)(x^2-1)=x^4-1
In addition:
(x-1)(x+1)=x^2-1, so we have:
(x^2+1)(x+1)(x-1)
As our complete factorization.
