There are 1 questions in this calculation: for each question, the 1 derivative of x is calculated.
    Note that variables are case sensitive.
\[ \begin{equation}\begin{split}[1/1]Find\ the\ first\ derivative\ of\ function\ 66(xx - 3x + 1)(xx - 3x + 1)\ with\ respect\ to\ x：\\\end{split}\end{equation} \]\[ \begin{equation}\begin{split}\\Solution:&\\ &Primitive\ function\ = 66x^{4} - 396x^{3} + 726x^{2} - 396x + 66\\&\color{blue}{The\ first\ derivative\ function：}\\&\frac{d\left( 66x^{4} - 396x^{3} + 726x^{2} - 396x + 66\right)}{dx}\\=&66*4x^{3} - 396*3x^{2} + 726*2x - 396 + 0\\=&264x^{3} - 1188x^{2} + 1452x - 396\\ \end{split}\end{equation} \]
