Consider expression
First, you can factor it:

Since x is integer number, then you can see that x-1 is previous integer number (x-1 is 1 unit smaller than x).
Therefore, x-1 and x are two consecutive integers. When you have two consecutive integers, one of them is always even and one is always odd. Multiplying even integer number by odd integer number you always get even integer number.
Thus,
is always even.
Answer:
-8/3 = d OR -2 2/3
Step-by-step explanation:
9d-4d-2d+8=-3d Well first combine all like terms
3d+8=-3d Now isolate the variable by subtracting 4d from both sides
3d(-3d) + 8= -3d (-3d)
8= -3d Divide both sides by -3
-8/3 = d OR -2 2/3
