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