Folllowing $\displaystyle \color{blue}{\textbf{MarkFL}}$'s suggestion, I edited the formula by erasing superscripts, subscripts and some symbols (in order to hide the original formula) which left the formula meaningless along with eccentric spacing. I just needed the idea of expanding the square brackets to cover the entire formula which I have got now. I didn't knew that an array can begin inside an array. The eqnarray and equation tags don't work in MathJax ?
