Full solution stays hidden until you ask for it.
1. Choose one side to transform.
2. Factor using common factors or special identities.
3. Show it matches the other side.
Use the worked steps, then substitute the final answer back into the original relationship to confirm it satisfies the prompt.
Only expanding when prompt requires factoring instead.
