There are 1 questions in this calculation: for each question, the 1 derivative of x is calculated.
    Note that variables are case sensitive.
\[ \begin{equation}\begin{split}[1/1]Find\ the\ first\ derivative\ of\ function\ 2x*25(125x + 1)*2 - 2(125x + 1) + 2\ with\ respect\ to\ x：\\\end{split}\end{equation} \]\[ \begin{equation}\begin{split}\\Solution:&\\ &Primitive\ function\ = 12500x^{2} - 150x\\&\color{blue}{The\ first\ derivative\ function：}\\&\frac{d\left( 12500x^{2} - 150x\right)}{dx}\\=&12500*2x - 150\\=&25000x - 150\\ \end{split}\end{equation} \]
