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