There are 1 questions in this calculation: for each question, the 1 derivative of x is calculated.
    Note that variables are case sensitive.
\[ \begin{equation}\begin{split}[1/1]Find\ the\ first\ derivative\ of\ function\ \frac{(2x - 1){e}^{x}}{x} - 1\ with\ respect\ to\ x：\\\end{split}\end{equation} \]\[ \begin{equation}\begin{split}\\Solution:&\\ &Primitive\ function\ = 2{e}^{x} - \frac{{e}^{x}}{x} - 1\\&\color{blue}{The\ first\ derivative\ function：}\\&\frac{d\left( 2{e}^{x} - \frac{{e}^{x}}{x} - 1\right)}{dx}\\=&2({e}^{x}((1)ln(e) + \frac{(x)(0)}{(e)})) - \frac{-{e}^{x}}{x^{2}} - \frac{({e}^{x}((1)ln(e) + \frac{(x)(0)}{(e)}))}{x} + 0\\=&2{e}^{x} + \frac{{e}^{x}}{x^{2}} - \frac{{e}^{x}}{x}\\ \end{split}\end{equation} \]
