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