There are 1 questions in this calculation: for each question, the 1 derivative of x is calculated.
    Note that variables are case sensitive.
\[ \begin{equation}\begin{split}[1/1]Find\ the\ first\ derivative\ of\ function\ \frac{({x}^{2} - x - 2{\frac{1}{x}}^{2}){e}^{1}}{x}\ with\ respect\ to\ x：\\\end{split}\end{equation} \]\[ \begin{equation}\begin{split}\\Solution:&\\ &Primitive\ function\ = xe - e - \frac{2e}{x^{3}}\\&\color{blue}{The\ first\ derivative\ function：}\\&\frac{d\left( xe - e - \frac{2e}{x^{3}}\right)}{dx}\\=&e + x*0 - 0 - \frac{2*-3e}{x^{4}} - \frac{2*0}{x^{3}}\\=&e + \frac{6e}{x^{4}}\\ \end{split}\end{equation} \]
