Determine whether rewrite (x^2-1)/(x+1) rewritten as x-1 loses restrictions.
Using a hint is okay. It just tells the trainer to give you a little more review.

Walkthrough
Full solution stays hidden until you ask for it.
1. Find the domain of the original expression.
2. Find the domain of the rewritten form.
3. Compare domains and identify any lost or added restrictions.
Use the worked steps, then substitute the final answer back into the original relationship to confirm it satisfies the prompt.
