Use synthetic division to perform the division
(2x^4 - 3x^3 + 2x - 5) divided by (3x + 2)

We have to put in a placeholder of 0x%5E2

%282x%5E4+-+3x%5E3+%2B+0x%5E2+%2B+2x+-+5%29÷%283x+%2B+2%29

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 3x%2B2 and get 3%28x%2B2%2F3%29
2. So we divide first synthetically by %28x%2B2%2F3%29 
3. Then  we divide by 3.

Dividing first by x%2B2%2F3

-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:

%2881%28%28-409%29%2F81%29%29%2F%2881%28x%2B2%2F3%29%29=%28-409%29%2F%2881x%2B54%29

So dividing by x%2B2%2F3 gives:

      

Now we must divide every term by 3, which is the same
as multiplying by 1%2F3:

      

What a terrible problem!  Are you sure you didn't copy something
wrong?
