Negative will mean less than zero, and positive will mean not less than or equal to zero.
Critical values are -5, -1, and 1. These values cut the x number line into intervals. Be aware than the roots are 1 and -1, so these will satisfy the inequality.
Not absolutely sure the format of your sign table.
__________________(-infin, -5]__________[-5, -1]____________[-1, 1]_________[1, infin)

SIGNS_____________(+)(-)/(-)__________(+)(-)/(-)___________(+)(+)/(+)________(-)(+)/(+)

RESULT SIGN________(+)________________(+)_________________(+)________________(-)
If I made no logic mistakes here, then the interval which satisfies is
. The root value
also satisfies the inequality.
