There are 2 questions in this calculation: for each question, the 1 derivative of x is calculated.
Note that variables are case sensitive.\[ \begin{equation}\begin{split}[1/2]Find\ the\ first\ derivative\ of\ function\ -1.5{x}^{2} + {(-1.2 - 0.75x)}^{2}\ with\ respect\ to\ x:\\\end{split}\end{equation} \]
