\[\int\limits_{}^{}\ln(2x+1)dx = x*\ln(2x+1) - \int\limits_{}^{}\frac{ 2x }{ 2x +1 }\]

I don't know how to take the integral of 2x / 2x + 1. I've viewed solutions online and I've seen...

I don't know why they split it into (2x - 1 + 1)/2x +1 Everything else I can do, except I just don't understand that part

lol, i'm not gonna lie, it's been a while. but i can do it! thanks for answering. The way I initially approached it was by doing \[2\int\limits_{}^{}x * \frac{ 1 }{ 2x +1 }\] and then using \[uv - \int\limits_{}^{}vdu\] to solve. so maybe that's why i didn't initially think of doing long division

that gives you back the original integrand haha!
