5x + 6x³ - 8  divided by x - 2

Write 5x + 6x³ - 8  in descending order

6x³ + 5x - 8  

Insert "+ 0x²" as a placeholder for a term in x²

6x³ + 0x² + 5x - 8 

You can either use long division or synthetic division:

Long division:



             6x² + 12x + 29 + 50%2F%28x-2%29
x - 2)6x³ +  0x² +  5x -  8
      6x³ - 12x²
            12x² +  5x
            12x² - 24x
                   29x -  8
                   29x - 58
                         50 
Or by synthetic division:

    2| 6  0  5  -8
     |   12 24  58 
       6 12 29  50 

   6x² + 12x + 29 + 50%2F%28x-2%29
