Full solution stays hidden until you ask for it.
1. Substitute the candidate root or inspect factors.
2. Simplify the polynomial value.
3. Conclude root only if the value is zero.
Use the worked steps, then substitute the final answer back into the original relationship to confirm it satisfies the prompt.
Relying on approximate graph only for nonreal roots.
