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