Answer:
3x² - x - 1 -

Explanation:
given the polynomial , divide by x - 1
using synthetic division with divisor x - 1 = 0 , then x = 1
the dividend consists of the coefficients of the polynomial.
note the x- term's coefficient is zero
1 | 3 - 4 0 - 1
↓ 3 - 1 - 1
---------------------
3 - 1 - 1 - 2 ← remainder [ 3 , - 1, - 1 are the coefficients of the quotient ]
quotient is of degree 1 less than the dividend
quotient is 3x² - x - 1
thus the result of the division is
3x² - x - 1 -
