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