There are 1 questions in this calculation: for each question, the 1 derivative of x is calculated.
    Note that variables are case sensitive.
\[ \begin{equation}\begin{split}[1/1]Find\ the\ first\ derivative\ of\ function\ x + \frac{3*2}{x} - 5x + 6\ with\ respect\ to\ x：\\\end{split}\end{equation} \]\[ \begin{equation}\begin{split}\\Solution:&\\ &Primitive\ function\ = -4x + \frac{6}{x} + 6\\&\color{blue}{The\ first\ derivative\ function：}\\&\frac{d\left( -4x + \frac{6}{x} + 6\right)}{dx}\\=&-4 + \frac{6*-1}{x^{2}} + 0\\=& - \frac{6}{x^{2}} - 4\\ \end{split}\end{equation} \]
