There are 1 questions in this calculation: for each question, the 1 derivative of x is calculated.
    Note that variables are case sensitive.
\[ \begin{equation}\begin{split}[1/1]Find\ the\ first\ derivative\ of\ function\ {(1 - \frac{a}{x})}^{2}\ with\ respect\ to\ x：\\\end{split}\end{equation} \]\[ \begin{equation}\begin{split}\\Solution:&\\ &Primitive\ function\ = \frac{a^{2}}{x^{2}} - \frac{2a}{x} + 1\\&\color{blue}{The\ first\ derivative\ function：}\\&\frac{d\left( \frac{a^{2}}{x^{2}} - \frac{2a}{x} + 1\right)}{dx}\\=&\frac{a^{2}*-2}{x^{3}} - \frac{2a*-1}{x^{2}} + 0\\=&\frac{-2a^{2}}{x^{3}} + \frac{2a}{x^{2}}\\ \end{split}\end{equation} \]
