If x is an integer, then x(x – 1)(x – k) must be evenly divisible by three when k is any of the following values EXCEPT	Choose the most appropriate option
A) -4  B) -2  C) -1  D) 2  E) 5
There is probably an easier way, but I just used the picking numbers option for this.   I chose x=2   2(1)(2-k) then just plugged in the answer choices for K until one wasn't evenly divisible by 3.   B gives you 8. 8/3 is not an integer.   -2 is the answer
