(n³ + 9n² - 7n + 23)÷(n + 10)

                n²  -   n +  3
n + 10)  n³ +  9n²  -  7n + 23
       -(n³ + 10n²)
               -n²  -  7n
             -(-n²  - 10n)
                       3n + 23
                     -(3n + 30)
                            -7

Answer:  n² - n + 3 + 

or

         n² - n + 3 - 

or you can do it by synthetic division:

-10|1   9  -7   23
   |  -10  10  -30
    1  -1   3   -7 

Same answer.
