Full solution stays hidden until you ask for it.
1. Identify degree and known roots.
2. Apply FTA and conjugate-pair theorem if applicable.
3. Correct the count or root list.
Use the worked steps, then substitute the final answer back into the original relationship to confirm it satisfies the prompt.
Graph-only root count when complex roots are required.
