What are you attempting to achieve?
You can restore your iPad either from an existing iCloud/iTunes backup - or to Factory Settings. Whilst the core process is essentially the same, the two options have somewhat different outcomes:
Restore your iPhone, iPad or iPod touch from a backup – Apple Support
Restore your iPhone, iPad or iPod to factory settings – Apple Support
