There are 1 questions in this calculation: for each question, the 1 derivative of x is calculated.
    Note that variables are case sensitive.
\[ \begin{equation}\begin{split}[1/1]Find\ the\ first\ derivative\ of\ function\ (10x + 14)(1.4522 - x) - 24*0.4522\ with\ respect\ to\ x：\\\end{split}\end{equation} \]\[ \begin{equation}\begin{split}\\Solution:&\\ &Primitive\ function\ = 14.522x - 10x^{2} - 14x + 9.478\\&\color{blue}{The\ first\ derivative\ function：}\\&\frac{d\left( 14.522x - 10x^{2} - 14x + 9.478\right)}{dx}\\=&14.522 - 10*2x - 14 + 0\\=& - 20x + 0.521999999999998\\ \end{split}\end{equation} \]
