We usually set up division as
divisor $)\overline{\text{ dividend }}$
The divisor and dividend can be polynomials, in which case we perform polynomial division.
When the divisor is a polynomial $(x-a)$ we can use synthetic division.
Here, $a=1$.
With synthetic division,
in the divisor placeholder, we place $a,$
and in the dividend, we list ALL coefficients (including the zeros ), starting from highest power of x.
