Hello,
I'll walk you through this and see if it makes sense.
x^3-3x^2+3x-9
Work with the first two terms and then the last two terms to give us:
x^2(x-3)+3(x-3) Now watch,since we have two (x-3) we can do the following:
(x^2+3)(x-3)
There we go. It's factored.

factor: +x%5E3-3x%5E2%2B3x-9+
x^2(x-3)+3(x-3)
(x^2+3)(x-3) --> check with foil (first outer inner last)
x^3-3x^2+3x-9
