Use synthetic division to solve open paren x to the 4th power minus 1 close paren divided by open paren x minus 1 close paren What is the quotient?

For synthetic division by x − 1, use 1 as the divisor’s zero and the coefficients 1, 0, 0, 0, −1. The quotient coefficients are 1, 1, 1, 1, with remainder 0, so the quotient is x³ + x² + x + 1. This is choice C.
