Hello Student,
Please find answer to your question below

I = \int \frac{2x}{(2x+1)^2}dx
I = \int \frac{2x+1-1}{(2x+1)^2}dx
I = \int [\frac{1}{2x+1}-\frac{1}{(2x+1)^2}]dx
I = \int \frac{1}{2x+1}dx-\int \frac{1}{(2x+1)^2}dx
I = \frac{log(2x+1)}{2}-\int \frac{1}{(2x+1)^2}dx
I = \frac{log(2x+1)}{2}+ \frac{1}{2(2x+1)}+c
