First we should simplify the expression to be able to integrate it. We should separate the expression to 2 parts. Now we have the following: 2/x^2 + 4xWe can bring the x^2 to the top,now we have the following: 2x^-2 + 4xnow we can integrate this. This becomes: 2x^-1 / -1 + 4x^2 / 2 which can be simplified to: -2/x + 2x^2
