Best ResponseYou've already chosen the best response.1the first thing I do is make sure I got all the exponents; you need a complete set in order to perform it proerly; any missing parts get zeroed out this is good tho: 3,2,1,0 is all there so strip the coeffs and their signs and put them in a row

Best ResponseYou've already chosen the best response.1c1 c2 c3 c4 next we want a row that we will fill in to add these coeffs too; and start it with a 0 c1 c2 c3 c4 0  <this next row we will fill in with the sums from the top and multiply them to our "root" c1 c2 c3 c4 0  r ) c1 then we just follow thru like a synthD machine c1 c2 c3 c4 0 rc1 r(rc1+c2) r(r(rc1+c2)+c3)  r ) c1 rc1+c2 r(rc1+c2)+c3 with any luck this is a 0 on the end, otherwise its the remainder the under side there is our quotient

Best ResponseYou've already chosen the best response.1the quotient is one degree less that what we started with; in this case we drop from x^3 to x^2

Best ResponseYou've already chosen the best response.1you do all the parts of longhand ... so its not any more complicated, in fact its a smidge simpler

Best ResponseYou've already chosen the best response.1our "root" is going to be from the (x3) = 0 part; our root is when x=3 so instead of subtracting our result as in longhand, we already take care of that by swapping signs from 3 to 3 and then add. root here = 3

Best ResponseYou've already chosen the best response.1we have a remainder left over; but the quotient is still the same; all the numbers up to the last column

Best ResponseYou've already chosen the best response.1x3 + 7x2 + 5x – 20 ; opps, our divider is (x+3) :) so root is 3 lol x3 + 7x2 + 5x – 20 0 3 12 21  3) 1 4 7 R=1

Best ResponseYou've already chosen the best response.1since the variables dont actually play into the process, they strip them; but i find it rather pointless to say they HAVE to not be there; it leads to confusion alot i think
