Can somebody explain what the justification for turning dx into 3u^2du? Like i understand that it will reverse the chain rule but the entire funtion changes right?

Brainlet here, what is the justification for turning dx into 3u^2 du, like i get that you're trying to reverse the chain-rule and all but doesn't the expresion change?
