There are 1 questions in this calculation: for each question, the 1 derivative of x is calculated.
    Note that variables are case sensitive.
\[ \begin{equation}\begin{split}[1/1]Find\ the\ first\ derivative\ of\ function\ 1000(1 + 0.86x + {x}^{2})\ with\ respect\ to\ x：\\\end{split}\end{equation} \]\[ \begin{equation}\begin{split}\\Solution:&\\ &Primitive\ function\ = 860x + 1000x^{2} + 1000\\&\color{blue}{The\ first\ derivative\ function：}\\&\frac{d\left( 860x + 1000x^{2} + 1000\right)}{dx}\\=&860 + 1000*2x + 0\\=&2000x + 860\\ \end{split}\end{equation} \]
