Question 240747
a. We'll use Synthetic division. Since Synthetic Division is for dividing by an expression of the form (x-a), we will think of (x+2) as (x-(-2)):
<pre>
-2 |   2   -5   -4    7
----       -4   18  -28 
      ------------------
       2   -9   14  -21
</pre>
So the remainder is -21.<br>
b. By the Remainder Theorem, this is the same as part (a): -21.
