  1. x^3 - 12x^2 + 35x

    x(x^2 - 15x + 35)

    Solve it as in find x?

    Help me?

  2. x^3-12x^2+35x=0

    x(x^2-12x+35) = 0

    x(x-5)(x-7) = 0

    so, x = 0

         x-5 = 0 ==> x = 5

         x-7 = 0 ==> x = 7


  3. First Step Factor out the X

    x(X^2 - 12x + 35)

    Second Step

    X(X - 7)(X - 5)

    Third Step

    X=0, X=7, X=5

    Those are your three answers since you started with a cube root.
