Can you teach me how to do long division?

OpenStudy (luigi0210):

Any specific examples..?

OpenStudy (anonymous):

I can teach you my more kid-friendly approach to long division, if that's okay with you.

OpenStudy (christos):

2x^3-3x^2-36x+5

What are you dividing it by?

OpenStudy (christos):

OpenStudy (christos):

No can you teach me please

OpenStudy (luigi0210):

Synthetic division is like upside down division. So for the problem \[\frac{ 2x^3-3x^2-36x+5 }{ x-5 }\] It would look like this: |dw:1368504397441:dw|
