  1. when you divide two powers with the same base, keep the base and subtract the exponents.

    S^8/S^5 = S^(8-5) = S^3

    -4x^3+9x^2-6x-1

    What do you want done with it? Factor it?
    I think you have a typo.
    I think it should have been -4x^3+9x^2-6x+1 then the factors would be
    -(x-1)(x-1)(4x-1)
