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