The other tutor divided the wrong way.

x - 3 divided by x^3 + x^2 - 10x - 6



Write it as 



Multiply by 










The denominator is 

So we divide it out:

Either by long division or synthetic division:

            x² +  4x + 2          3|1  1  -10  -6
x - 3)x³ +  x² - 10x - 6           |   3   12   6 
      x³ - 3x²                      1  4    2   0 
           4x² - 10x              x² + 4x² + 2  
           4x² - 12x
                  2x - 6
                  2x - 6 


Therefore
