We can find the quotient and remainder when x^4 + 1 is divided by x^2 + 1 using long division.

x^2 + 1 | x^4 + 1................| x^2 - 1

...............x^4 + x^2

-------------------------------------

.......................1 - x^2

......................-1 - x^2

------------------------------------

.......................2

**The required quotient is x^2 - 1 and the remainder is 2.**

x^4+1 divided by x^2+1 = x^2 is quotient x^4+1- (x^2+1)x^2 = -x^2+1 is reminder.

-x^2+1 divided by x^2+1 = = -1 is quotient -x^2+1-(x^2+1)(-1) = 2 is reminder.

So x^4+1 divided by x^2+1 =** x^2-1 quotient and the remainder = 2**.
