To add or subtract expressions, expand them to make their denominators the same. Multiply X⁴ -1 times X/X.
( X⁴ - 1 ) X. 1
--------------- - ------
X. X
Since,
( X⁴ - 1 ) X
--------------
X
and
1
--
X
have the same denominator, subtract them by subtracting their numerators.
( X⁴ - 1 ) X - 1
------------------
X
Do the multiplication in ( X⁴ -1 ) X -1.
Then We get:-
X⁵ - X - 1
-------------
X
Hope it help you.
