To learn how to use long polynomial division, try

Note: You may want to put " inside your division, to help make room for the various terms you'll have when you do the subtractions.

If you get stuck, please reply showing your steps and reasoning so far. It will probably prove helpful to use "pre" tags for your formatting, like this:

Code: Select all

`[pre]my work:`

2x

----------------------

x^2 - 4 ) 2x^3 - 1x^2 - 1x + 0

2x^3 - 8x

----------------------

- 1x^2 + 7x + 0[/pre]

...which displays as:

my work:

2x

----------------------

x^2 - 4 ) 2x^3 - 1x^2 - 1x + 0

2x^3 - 8x

----------------------

- 1x^2 + 7x + 0

Thank you!
