i got this problem:3x^3-6x^2-24x
it says to factor it, well, i got the common factor 3x and i ended up with
3x(x-2x-8x) what did i do wrong? or did i do somethin' wrong?

....you got the common factor right which is 3x.
you have divide 3x into all the three numbers and it will look like this:
..................3x(x^2-2x-8)

next you simplify it and it will look something like this:
..................3x (x-4) (x+2)
