Hi, I'm beginner to calculus and I forgot my algebra because I stop my study for years. Now I don't know what next after I plug the value to the formula of quotient rule in derivate.
This is the given.
Then I think this is the derivative of the given function, but how to solve or factor or simplify this?
If you can show me the full solution then explain what process did you do, it will help me alot. Thanks
