I have a big equation which has a square root encompassing a major portion. I need to line-break it into multiple lines in latex. The original code that I have is given below:
\documentclass{article}\usepackage{amsmath} \begin{document}\begin{equation} \lambda = \sqrt{\frac{3}{2}}\left(\frac{1}{\tilde{r} \left(\tilde{g}^2+\tilde{r}^2\right)^{7/4} \tilde{r_h}}\right)\sqrt{\left(-\left(\left(-\frac{\tilde{r}^2 \left(\tilde{r_h}{}^2+1\right) \left(\frac{\tilde{g}^2+\tilde{r_h}{}^2}{\tilde{g}^2+\tilde{r}^2}\right){}^{3/2}}{\tilde{r_h}{}^2}+\tilde{r}^2+1\right) \left(2 \tilde{g}^6 \sqrt{\tilde{g}^2+\tilde{r}^2} \tilde{r_h}{}^2+\tilde{g}^4 \left(\tilde{r}^4 \left(\tilde{r_h}{}^2+1\right) \sqrt{\tilde{g}^2+\tilde{r_h}{}^2}+6 \tilde{r}^2 \sqrt{\tilde{g}^2+\tilde{r}^2} \tilde{r_h}{}^2\right)+\tilde{g}^2 \tilde{r}^4 \left(\tilde{r_h}{}^4 \sqrt{\tilde{g}^2+\tilde{r_h}{}^2}+\tilde{r_h}{}^2 \left(-4 \tilde{r}^2 \sqrt{\tilde{g}^2+\tilde{r_h}{}^2}+\sqrt{\tilde{g}^2+\tilde{r_h}{}^2}+6 \sqrt{\tilde{g}^2+\tilde{r}^2}\right)-4 \tilde{r}^2 \sqrt{\tilde{g}^2+\tilde{r_h}{}^2}\right)+2 \tilde{r}^6 \tilde{r_h}{}^2 \left(-2 \tilde{r_h}{}^2 \sqrt{\tilde{g}^2+\tilde{r_h}{}^2}-2 \sqrt{\tilde{g}^2+\tilde{r_h}{}^2}+\sqrt{\tilde{g}^2+\tilde{r}^2}\right)\right)\right)\right)}\end{equation}\end{document}I tried using aligned, split, multline, with various option like \biggl, \biggr, \left., \right. but none of them seem to work. What is the best way to break such an equation across multiple lines? Any help in this regard would be truly beneficial.
