can you help me with this factoring question?

the exact question says "factor the expression completely".
I am a non-traditional student studying algeba and trigonometry on my own.

I am also stuck with the next question

(x+1)^3x-2(x+1)^2x^2+x^3(x+1)

I tried grouping like terms but I can't even get started. Please let me know if I am still not following the rules.
 
I tried. Having trouble.

a(b^2)-b(a^2)
ab^2-a^2(b)
(a)(b)(b)-(a)(a)(b)
(b)(-a^2+a+b)
??
 
(x-1) (x+2)[(x+2)-(x-1)]

? however this is not the answer in the textbook. it may have been factored more.


 
(x-1) (x+2)[(x+2)-(x-1)]

Right - but you need to simplify this part to get correct answer.
 
thanks. would you mind helping me with that? I seem to be having trouble.
