Full solution stays hidden until you ask for it.
1. Factor out the greatest common factor.
2. Factor the remaining expression if possible.
3. Use zero-product property on variable-containing factors.
Use the worked steps, then substitute the final answer back into the original relationship to confirm it satisfies the prompt.
Treating the nonzero numerical GCF as a zero.
