I tried to solve this integral and got it, I showed firstly $$\int_0^1 \frac{\ln^2(x+1)+\ln^2\left(\frac{x}{x+1}\right)}{x^2+1} dx=2\Im\left[\text{Li}_3(1+i) \right] $$ and for other integral $$\int_0^1 \frac{\ln\left(\frac{2x}{x^2+1}\right)\ln x}{x^2+1} dx=\int_0^1 \frac{\left(\ln2+\ln x\right)\ln x}{x^2+1} dx-\int_0^1 \frac{\ln\left(x^2+1\right)\ln x}{x^2+1} dx$$ then by using series and its value $$ \int_0^1 \frac{\left(\ln2+\ln x\right)\ln x}{x^2+1} dx=-G\ln2+\frac{\pi^3}{16}$$ $$ \int_0^1 \frac{\ln\left(x^2+1\right)\ln x}{x^2+1} dx=\sum_{k=1}^{\infty}(-1)^{n-1}H_n \int_0^1x^{2n}\ln x dx $$ $$=\sum_{k=1}^{\infty} \frac{(-1)^{n} H_n}{(2n+1)^2} =2\Im\left[\text{Li}_3(1+i) \right]+\frac{3}{32}\pi^3+\frac{\pi}{8}(\ln2)^2-G\ln2$$ then got the result $$\int_0^1 \frac{\ln^2(x+1)-\ln\left(\frac{2x}{x^2+1}\right)\ln x+\ln^2\left(\frac{x}{x+1}\right)}{x^2+1} dx=\frac{\pi}{8} \left(\frac{\pi^2}{4}+(\ln2)^2\right)$$ MY QUESTION
How can I get the result with simple way without using complicated constants and values of some series which are long to prove it?
