There are 1 questions in this calculation: for each question, the 1 derivative of x is calculated.
    Note that variables are case sensitive.
\[ \begin{equation}\begin{split}[1/1]Find\ the\ first\ derivative\ of\ function\ {(\frac{61}{28} + x)}^{2} - \frac{2*17(\frac{61}{28} + x)}{28} - 4(\frac{61}{28} + x)\ with\ respect\ to\ x：\\\end{split}\end{equation} \]\[ \begin{equation}\begin{split}\\Solution:&\\ &Primitive\ function\ = x^{2} - \frac{6}{7}x - \frac{5185}{784}\\&\color{blue}{The\ first\ derivative\ function：}\\&\frac{d\left( x^{2} - \frac{6}{7}x - \frac{5185}{784}\right)}{dx}\\=&2x - \frac{6}{7} + 0\\=&2x - \frac{6}{7}\\ \end{split}\end{equation} \]
