x3 - x2 - 2x +2 you can divide this into two parts for now x3 - x2 and -2x +2 factor out everything you can from both x2(x-1) and -2(x+1) since the insides of the parentheses are the same, we can put them together, then multiply it by the sum of the two parts outside the parentheses. (x-1)(x2-2)
3x2 + 2x + 3 + x2 + x + 1 = 4x 2+ 3x + 4
14x2 + 15x + 4 = (7x + 4)(2x +1)
4X + 2x = 1. Where x = 0.166666666666666666666666666666666666666 recurring.
