$\underline{4}|\ \ 1\ \ 5\ -7\ \ 1$
Synthetic Division To divide a polynomial by $x-c$: 1. Arrange the polynomial in descending powers, with a $0$ coefficient for any missing term. 2. Write $c$ for the divisor, $x-c$. To the right, write the coefficients of the dividend. $...$ ----------- c=4, and the coefficients of the dividend are 1, 5, -7, 1. (none are missing) So our first step is to write $\underline{4}|\ 1\ 5\ -7\ 1$
