What do you think?
Actually If we assume , What will happen?
How will find v in that case ?
And suggest to take
Well clearly we would need to get the integral of dv. I know the integral of ln x is x ln x - x + C, but what would it be considering that it's 2x in our problem?

And this becomes by using integration by parts ! You will make integration by parts to find your v. then you will do integration by parts for the main integral!

For your question about :

Thank you for the detailed response, daddy-o. And you're right, it's actually easier if you set dv as 7x.
