Which of the following represents the factored form of f(x) = x3 − 64x? f(x) = x(x + 8)(x − 8) f(x) = (x − 8)(x + 8) f(x) = x(x − 8)2 f(x) = x(x2 − 8)

    Well The factors of 64 are: 1, 2, 4, 8, 16, 32, 64

    Yes the variables they are both X making them common I guess

    yes smallest degree variable will be the common factor |dw:1439587179653:dw| take out the common factor what ill you have left in the parentheses ?

    in other words divide both terms by common factor \[\huge\rm x^3-64x\] \[\huge\rm \frac{ x^3 }{ x }-\frac{ 64x }{ x } = x(?? - ??)\]
