Find the Remainder x^5-1 is divided by x-1

$x^{5} - 1$ is divided by $x - 1$

Write the problem as a mathematical expression.

$\frac{x^{5} - 1}{x - 1}$

To calculate the remainder, first divide the polynomials.

Set up the polynomials to be divided. If there is not a term for every exponent, insert one with a value of $0$ .
