Question 1028961
Set the format for the division this way:

<pre>
    -1    |      1        3      0      0      3      -7
          |
          |
          |_______________________________________________________


</pre>
This setup is for checking the possible root of {{{-1}}}, and the coefficients of the dividend must include all degrees of x.  The remainder WILL BE  P(-1).


<pre>
    -1    |      1        3      0      0      3      -7
          |
          |              -1     -2       2    -2      -1
          |_______________________________________________________
                 1       2      -2      2      1    <b>{{{highlight(-8)}}}</b>

</pre>
