haven't done factoring in a while :/ factor out (x-1) from x^{4}-5x^{3}+9x-7x+2

Use polynomial long division.
Long division is correct: You just divide like any other type of long division. To give you a reference, the answer should be x^3 - 4x^2 + 5x - 2. If you are doing homework, I'm sure your teacher wants all the steps involved.
could do synthetic division in this case ... little less painful
