Ok, so you split up into two intervals I did from 2x to 0 and 0 to 4x.

Then you reverse the 2x to 0 and the integral becomes negative.

Then, replace 2x and 4x with u and chain rule

answer: (-2(x)^{2}-5/(2x)^{2}+5)*2 + (4(x)^{2}-5/(4x)^{2}+5)*4

Is my work correct? I was marked wrong and it said we didnt have to simplify.
