SOLUTION: Factor the expression:
(x-1)^3+1
This is as far as I got:
(x-1) (x-1) (x-1)+1
Then I tried to factor by grouping the four terms
x-1(1) 1(x-1)
I'm lost.

You can put this solution on YOUR website! (x-1)* (x-1) *(x-1)+1
You have to multiply it out all the way and add terms before you can factor
x^3-3x^2+3x
x*(x^2-3x+3)
You can put this solution on YOUR website! Factor the expression:
(x-1)^3+1
---------
It's the sum of 2 cubes.
Sub y for x-1
-------
then sub x-1 for y
=
=
