Problem 53 of 7
Factor out the GCF, then use another structure to factor 7x^2-7 completely.
Using a hint is okay. It just tells the trainer to give you a little more review.

sequence GCF then special pattern.
Hidden until you reveal it.
Expression must have a nontrivial GCF and then a recognizable special pattern.
Enter your answer
Your answer is equivalent to the expected form.
Walkthrough
Full solution stays hidden until you ask for it.
1. Factor out the greatest common factor first.
2. Inspect the remaining expression for difference-of-squares or perfect-square structure.
3. Factor the remaining structure completely.
Use the worked steps, then substitute the final answer back into the original relationship to confirm it satisfies the prompt.
Stopping after only factoring out the GCF when a special pattern remains.
