X+2=0 satisfies the condition that the zeroth power of any number is equal to 1 x=-2.

X+2= positive number. If X+2= 1 does not satisfy x+2=2 x=0, then x+2=3 is not satisfied.

X+2= negative X is definitely negative x- 1 is definitely negative, and the negative power of negative is definitely not 1.

So the answer is -2, 0 2.
