There are 1 questions in this calculation: for each question, the 1 derivative of x is calculated.
    Note that variables are case sensitive.
\[ \begin{equation}\begin{split}[1/1]Find\ the\ first\ derivative\ of\ function\ (x - 1)(x + 1)(x - 4)(x - 7)(x - 8)\ with\ respect\ to\ x：\\\end{split}\end{equation} \]\[ \begin{equation}\begin{split}\\Solution:&\\ &Primitive\ function\ = x^{5} - 19x^{4} + 115x^{3} - 205x^{2} - 116x + 224\\&\color{blue}{The\ first\ derivative\ function：}\\&\frac{d\left( x^{5} - 19x^{4} + 115x^{3} - 205x^{2} - 116x + 224\right)}{dx}\\=&5x^{4} - 19*4x^{3} + 115*3x^{2} - 205*2x - 116 + 0\\=&5x^{4} - 76x^{3} + 345x^{2} - 410x - 116\\ \end{split}\end{equation} \]
