3rd degree polynomial

  1. Mar 30, 2008 #1
    -x^3+6x^2-12x+8=0




    3. The attempt at a solution

    - this is actually part of an eigenvalue problem, but I can't seem to remember how to factor 3rd degree polynomials. Any thing to help me remember would be great.

    well by investigation we can see that 2 is a root of that equation, now can u perform synthetic division, or devide that polynomial by (x-2).
