Hi, this is my problem x cubed-x squared - 4x + 4 equals 0. And it states factor by grouping. I know to take out a common factor from terms so is the common factor x squared?

\(\displaystyle x^3 \ - \ x^2 \ - 4x \ + \ 4\)

\(\displaystyle x^2 \ * \ (x \ - \ 1) \ - 4 \ * \ (x \ - \ 1)\)

Now continue.....
