    Depends what the question asks in relation to the equation. Looks to me like it might need deriving. Possibly factorising. Care to elaborate Dara?

    I don't know how to do this, they just ask to devide this polynomial equation

    it is like long dividing regular numbers only you use 3x+1 | 3x^3-5x^2+10x-3, so the first element of answer becomes x^2. (3x+1)(x^2) = 3x^3 +x^2, so you write this under the polynomial and subtract it like you would an integer. -9x^2 remains, bring down the 10x, so the next element is -3x, multiply it so on and so forth. When you come to the end and have a remainder, it is added to the answer as + r/3x+1. You should be alright.
