Do you want polynomial division or do you want synthetic division? Either way, same final result.

Here's using synthetic division:

7___|___5____-32____-21
____|___.____35_____21
____|_________________
________5____3______0__......showing remainder is zero.


The quotient is highlight%285x%2B3%29. You can check if desired, by doing multiplication %28x-7%29%2A%285x%2B3%29. What do you find?
