There are 1 questions in this calculation: for each question, the 1 derivative of x is calculated.
    Note that variables are case sensitive.
\[ \begin{equation}\begin{split}[1/1]Find\ the\ first\ derivative\ of\ function\ 3o{x}^{2} + 6p(1 - x)x + 3q{(1 - x)}^{2}\ with\ respect\ to\ x：\\\end{split}\end{equation} \]\[ \begin{equation}\begin{split}\\Solution:&\\ &Primitive\ function\ = 3ox^{2} + 6px - 6px^{2} + 3qx^{2} - 6qx + 3q\\&\color{blue}{The\ first\ derivative\ function：}\\&\frac{d\left( 3ox^{2} + 6px - 6px^{2} + 3qx^{2} - 6qx + 3q\right)}{dx}\\=&3o*2x + 6p - 6p*2x + 3q*2x - 6q + 0\\=&6ox - 12px + 6p + 6qx - 6q\\ \end{split}\end{equation} \]
