A question from Integration Bee 2022: Evaluate $\int^2_{1/2}\ln(\frac{\ln(x+\frac{1}{x})}{\ln(x^2-x+\frac{17}{4})})dx$ I am trying to evaluate the integral $$\int^2_{\frac{1}2}\ln\left(\frac{\ln(x+\frac{1}{x})}{\ln(x^2-x+\frac{17}{4})}\right)dx$$ by separating it as $$\int^2_{\frac{1}2}\ln\ln\left(x+\frac{1}{x}\right)dx-\int^2_{\frac{1}2}\ln\ln\left(\left(x-\frac{1}{2}\right)^2+4\right)dx$$
I think the substitution $x=1/u$ should be applied for the first item but I don't know how to go on. Please help. Thank you. (The final answer is $-\frac{3}{2}\ln2$)

Separately
\begin{align}
\hspace{-10mm}\int^2_{1/2}\ln\ln(x^2-x+\frac{17}{4})dx\overset{x-\frac12\to x}
= \int^{3/2}_{0}\ln\ln(x^2+4)\ dx \\
\end{align}
\begin{align}
\int^2_{1/2}\ln\ln\left(x+\frac{1}{x}\right)\overset{x\to \frac1x}{dx}
= &\ \frac12 \int^2_{1/2}\ln\ln\left(x+\frac{1}{x}\right)(1+\frac1{x^2})\overset{x-\frac1x\to x}{dx}\\
=&\ \frac12 \int^{3/2}_{-3/2} \ln \frac12 + \ln\ln(x^2+4)\ dx \\
 = &-\frac32 \ln2 +\int^{3/2}_{0} \ln\ln(x^2+4)\ dx \\
\end{align}
Together
$$\int^2_{1/2}\ln\frac{\ln(x+\frac{1}{x})}{\ln(x^2-x+\frac{17}{4})}dx=-\frac32 \ln2
$$
