There are 1 questions in this calculation: for each question, the 1 derivative of x is calculated.
    Note that variables are case sensitive.
\[ \begin{equation}\begin{split}[1/1]Find\ the\ first\ derivative\ of\ function\ {(7 - 14x)}^{2} + \frac{7{(1 - 7x)}^{2}}{2}\ with\ respect\ to\ x：\\\end{split}\end{equation} \]\[ \begin{equation}\begin{split}\\Solution:&\\ &Primitive\ function\ = \frac{735}{2}x^{2} - 245x + \frac{105}{2}\\&\color{blue}{The\ first\ derivative\ function：}\\&\frac{d\left( \frac{735}{2}x^{2} - 245x + \frac{105}{2}\right)}{dx}\\=&\frac{735}{2}*2x - 245 + 0\\=&735x - 245\\ \end{split}\end{equation} \]
