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