    Like normal division, what would you need to multiply (r+2) by to get close to (r^6+0r-64)?

    If I gave you this:|dw:1336153681989:dw| How would you go about solving it?

    You would say, "what is the largest number I can multiply 6 by to get the first number?" Since 6 is greater than 4 you would ask the question again about 42. The same logic applies to your problem... What do I need to multiply 'r' by to get r^6?|dw:1336153892815:dw|

    \[ r^6-64=(r-2) (r+2) \left(r^2-2 r+4\right) \left(r^2+2 r+4\right) \] You can also factor before if it is permitted. Division will be easy by r+2

    Not even sure if basic division makes sense at this point. :p

    to be fair, 6 *n = 4 when n=4/6 :)

    notice that when we want to zero out the first term; we multiply by that term divded by the one on the outside same pattern applies to polys

    the key being, the top is just the division of the first terms each time till you decide to stop

    its no different form what they taught you back in the 3rd or 4th grade :) you just gotta practice it to get more confident at it, but theres nothing new to it overall

    wrong signs tend to be a result of forgeting that you are subtracting everything; just like normal: 8 -------- 4 ) 34 8(4) = 32 do we add or subtract the 32 to get the next line?

    correct, and its the same basic concept when using polys to; division is division no matter what you use
