Walkthrough
Full solution stays hidden until you ask for it.
1. Use factored form to identify the zeros.
2. Check which zeros make sense in context.
3. Explain what each valid zero represents.
Use the worked steps, then substitute the final answer back into the original relationship to confirm it satisfies the prompt.
