There are 1 questions in this calculation: for each question, the 1 derivative of x is calculated.
    Note that variables are case sensitive.
\[ \begin{equation}\begin{split}[1/1]Find\ the\ first\ derivative\ of\ function\ 2{x}^{2} + 2x{\frac{1}{(2x + 1)}}^{2}\ with\ respect\ to\ x：\\\end{split}\end{equation} \]\[ \begin{equation}\begin{split}\\Solution:&\\ &Primitive\ function\ = 2x^{2} + \frac{2x}{(2x + 1)^{2}}\\&\color{blue}{The\ first\ derivative\ function：}\\&\frac{d\left( 2x^{2} + \frac{2x}{(2x + 1)^{2}}\right)}{dx}\\=&2*2x + 2(\frac{-2(2 + 0)}{(2x + 1)^{3}})x + \frac{2}{(2x + 1)^{2}}\\=&4x - \frac{8x}{(2x + 1)^{3}} + \frac{2}{(2x + 1)^{2}}\\ \end{split}\end{equation} \]
