There are 1 questions in this calculation: for each question, the 1 derivative of y is calculated.
    Note that variables are case sensitive.
\[ \begin{equation}\begin{split}[1/1]Find\ the\ first\ derivative\ of\ function\ (4y - {y}^{2})(6 - 2x)\ with\ respect\ to\ y：\\\end{split}\end{equation} \]\[ \begin{equation}\begin{split}\\Solution:&\\ &Primitive\ function\ = 24y - 8xy - 6y^{2} + 2xy^{2}\\&\color{blue}{The\ first\ derivative\ function：}\\&\frac{d\left( 24y - 8xy - 6y^{2} + 2xy^{2}\right)}{dy}\\=&24 - 8x - 6*2y + 2x*2y\\=&4xy - 12y - 8x + 24\\ \end{split}\end{equation} \]
