There are 1 questions in this calculation: for each question, the 2 derivative of x is calculated.
    Note that variables are case sensitive.
\[ \begin{equation}\begin{split}[1/1]Find\ the\ second\ derivative\ of\ function\ \frac{4(x - 1)}{(xx)}\ with\ respect\ to\ x：\\\end{split}\end{equation} \]\[ \begin{equation}\begin{split}\\Solution:&\\ &Primitive\ function\ = \frac{4}{x} - \frac{4}{x^{2}}\\&\color{blue}{The\ first\ derivative\ function：}\\&\frac{d\left( \frac{4}{x} - \frac{4}{x^{2}}\right)}{dx}\\=&\frac{4*-1}{x^{2}} - \frac{4*-2}{x^{3}}\\=&\frac{-4}{x^{2}} + \frac{8}{x^{3}}\\\\ &\color{blue}{The\ second\ derivative\ of\ function:} \\&\frac{d\left( \frac{-4}{x^{2}} + \frac{8}{x^{3}}\right)}{dx}\\=&\frac{-4*-2}{x^{3}} + \frac{8*-3}{x^{4}}\\=&\frac{8}{x^{3}} - \frac{24}{x^{4}}\\ \end{split}\end{equation} \]
