    Simplifying by factoring

    Please any help with this question?
    If you could please let me know the steps for the answer.

    Simplifying this expression by factoring:

    [(x + 1) (x - 1)^2 - (x - 1)^3)]/[(x + 1)^2]

    Thank you in advance.

    \frac{(x + 1)(x - 1)^2 - (x - 1)^3}{(x + 1)^2}.

    Can you see that there is a common factor of (x - 1)^2 in the numerator?

    So \frac{(x + 1)(x - 1)^2 - (x - 1)^3}{(x + 1)^2} = \frac{(x-1)^2[x+1 - (x-1)]}{(x+1)^2}.


    Now simplify and see if you have any common factors in the numerator and denominator that can be cancelled.
