There are 1 questions in this calculation: for each question, the 1 derivative of x is calculated.
    Note that variables are case sensitive.
\[ \begin{equation}\begin{split}[1/1]Find\ the\ first\ derivative\ of\ function\ {(2x - 1)}^{2} + 2{(3x + 1)}^{2} - (2x - 1)(3x + 1) - 2x + 1\ with\ respect\ to\ x：\\\end{split}\end{equation} \]\[ \begin{equation}\begin{split}\\Solution:&\\ &Primitive\ function\ = 16x^{2} + 7x + 5\\&\color{blue}{The\ first\ derivative\ function：}\\&\frac{d\left( 16x^{2} + 7x + 5\right)}{dx}\\=&16*2x + 7 + 0\\=&32x + 7\\ \end{split}\end{equation} \]
