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