We have to put in a placeholder of ÷
Since synthetic division can only be used to divide
by expressions in the form x - A, we have to make two
divisions:
1. First we factor 3 out of and get
2. So we divide first synthetically by
3. Then we divide by 3.
Dividing first by
-2/3| 2 -3 0 2 -5
| -4/3 26/9 -52/27 -4/81
2 -13/3 26/9 2/27 -409/81
That gives
First we'll simplify that fraction on the end:
Multiply top and bottom by 81:
So dividing by gives:
Now we must divide every term by 3, which is the same
as multiplying by :
What a terrible problem! Are you sure you didn't copy something
wrong?
