1. The problem statement, all variables and given/known data I have a limit problem, however I do know how to work limits, I guess what I need is more of a refresher on how to work third degree polynomials. The polynomial(s) I am trying to work with are the following: x3-2x2+2x-15 -and- x3-5x2+10x-12 The limit is a limit where x approaches 3, so I believe that it is correct to assume that 3 is the rational root that we use in this case. However, my attempts haven't come up with a correct solution. I am just wondering where I have gone wrong and what I need to do to reach the correct answer. 2. The attempt at a solution x3-2x2+2x-15 x3-2x2+2x-15 ÷ x+3 First, I divide to get x2, then multiply x-3 by this to reach x3-3x2 Then I bring down 2x to get x2+2s Next I divide again to get x, then multiply x-3 again to reach x2-3x Finally I bring down -15 to get x-15. However if I divide again I get 1, but 1•-3 does not equal -15 so I get a remainder of 12. What am I doing wrong here?
