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