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 correct option
A) -4
B) -8
C) -1
D) 2
E) 5
if we put k=-1 we get:   X(x-1)(X+1) rearrange:(x-1)X(X+1)   so it looks like a sequenc,   if we assume that X =2 and put number from the answer then we get:   (x – 1)x(x – k)   k=5 =1.2.-3   k=2 =1.2.0   k=-1 =1.2.3   k=-4 =1.2.6   but when we put   k=-8 =1.2.10 not satisfied   so,the answer is -8
