There are 1 questions in this calculation: for each question, the 2 derivative of x is calculated.
    Note that variables are case sensitive.
\[ \begin{equation}\begin{split}[1/1]Find\ the\ second\ derivative\ of\ function\ 3{x}^{4} - 4{x}^{3} - 12{x}^{2} + 5\ with\ respect\ to\ x：\\\end{split}\end{equation} \]\[ \begin{equation}\begin{split}\\Solution:&\\ &Primitive\ function\ = 3x^{4} - 4x^{3} - 12x^{2} + 5\\&\color{blue}{The\ first\ derivative\ function：}\\&\frac{d\left( 3x^{4} - 4x^{3} - 12x^{2} + 5\right)}{dx}\\=&3*4x^{3} - 4*3x^{2} - 12*2x + 0\\=&12x^{3} - 12x^{2} - 24x\\\\ &\color{blue}{The\ second\ derivative\ of\ function:} \\&\frac{d\left( 12x^{3} - 12x^{2} - 24x\right)}{dx}\\=&12*3x^{2} - 12*2x - 24\\=&36x^{2} - 24x - 24\\ \end{split}\end{equation} \]
