There are 1 questions in this calculation: for each question, the 1 derivative of x is calculated.
    Note that variables are case sensitive.
\[ \begin{equation}\begin{split}[1/1]Find\ the\ first\ derivative\ of\ function\ (8{x}^{2} - 12)({x}^{5} - 120)\ with\ respect\ to\ x：\\\end{split}\end{equation} \]\[ \begin{equation}\begin{split}\\Solution:&\\ &Primitive\ function\ = 8x^{7} - 960x^{2} - 12x^{5} + 1440\\&\color{blue}{The\ first\ derivative\ function：}\\&\frac{d\left( 8x^{7} - 960x^{2} - 12x^{5} + 1440\right)}{dx}\\=&8*7x^{6} - 960*2x - 12*5x^{4} + 0\\=&56x^{6} - 1920x - 60x^{4}\\ \end{split}\end{equation} \]
