$(- 5, - 5, 5)$

Step 1

$(- 5, - 5, 5)$ is the same as ${- 5, 5}$ after removing the duplicate elements.

${- 5, 5}$

Step 2

The power set of a set $S$ is the set of all subsets of $S$ . The first subset will be set $S$ itself. Next, find all subsets that contain one less element (in this case $1$ elements). Continue with this process until finding all subsets including the empty set.

Power Set = ${{- 5, 5}, {- 5}, {5}, {}}$
