1. ## 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]

2. $\frac{(x + 1)(x - 1)^2 - (x - 1)^3}{(x + 1)^2}$.
Can you see that there is a common factor of $(x - 1)^2$ in the numerator?
So $\frac{(x + 1)(x - 1)^2 - (x - 1)^3}{(x + 1)^2} = \frac{(x-1)^2[x+1 - (x-1)]}{(x+1)^2}$.
