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