    The possible rational roots are the factors of the constant term divided by the factors of the coefficient of the leading term.

    The constant term is -6 The leading term is x^3 and its coefficient is 1

    So the possible rational roots are the factors of -6 divided by the factors of 1

    Let me give you an example: The factors of 12 are 4 and 3 because 4 x 3 = 12

    Also 2 and 6 are factors of 12 because 2 x 6 = 12

    Also -1 and -12 are factors of 12 because -1 x -12 = 12

    k so which do I choose from 1 and 2?

    this is an easy problem because the leading coefficient is 1 from x^3 so all those numbers can be divided by 1
