(x+1)^5-5x-2

f'(x)=5(x+1)^4-5

x=-2,0

if i make a sign chart, i would have to do all 4 factors (x+1) which means all negative signs would then be made positive.

but in the answer section, it says between -2 and 0, the function is decreasing, which means in the sign chart, it should be negative....

i hope im making sense..

what am i overlooking here?
