Answer 5

Make a note that when you factor something out of a fraction, you have to also exclude any cases where that thing would have been equal to zero (it is in the denominator that it is a problem because division is not defined for zero). Therefore, you can factor out x-1, but x=1 can no longer be considered as a possible value for x.
