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