For this question, we are going to factor the given polynomial completely, starting with synthetic division and then using factoring by grouping.

I did some investigative work and have found that x equals 1 is one of the zeros.

So i can use synthetic division, listing the coefficients of the given polynomial, bring down the one, multiply, combine, multiply, combine, multiply, combine, multiply, remainder of one.

So one of our factors, let me move that over, is x minus 1.

Now we are left with x cubed minus x squared plus 9x minus 9, which can be factored by grouping...
