Walkthrough
Full solution stays hidden until you ask for it.
1. Set the denominator not equal to zero.
2. Solve for excluded inputs.
3. Write the domain as all real numbers except those inputs.
Use the worked steps, then substitute the final answer back into the original relationship to confirm it satisfies the prompt.
Canceling a factor and forgetting the original excluded value.
