$\huge {\underbrace {\boxed {\orange{solution}}}}$

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
