    Who knows the formula to factor a cube?


    (x-1) will factor out to be (x - 3x + 3x - 1).

    There is some formula to do this without having to use a pencil or paper. I need to know it for my Math Final tomorrow.

    Thanks in advance.

    [size=1]Peace out fk. Thanks for all the good times .

    Pascal's Triangle

    This may reach you too late but, the way to expand polynomials quickly is by Pascal's triangle

    1 2 1
    1 3 3 1
    1 4 6 4 1
    1 5 10 10 5 1

    ie. your x^3 poly is expanded to the 3d row down or 1x^3+3x^2+3x+1
    or your x^5 is 1x^5+5x^4+10x^3+10x^2+5x+1
    To get more rows add the numbers diagonally above the space that you are trying to fill.
    Hope this helps.
