I find it helpful to take the 2 out of the integral (not needed but is good practice for harder questions), then it's just a case of integrating 1/x which you should be able to do, then applying limits and messing with the rules of logs.

Thank you so much for the help- I get it now. Sorry, I realise I've asked help for a fairly simple question, but I missed this topic in school. Thanks again! ☺️
