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