Cac bạn giúp minh bai nay Vs =(( 🤓🤓

$\begin{array}{l} a)\left( P \right)\,di\,qua\,A\left( { - 2;3} \right) \Rightarrow \left\{ \begin{array}{l} x = - 2\\ y = 3 \end{array} \right.\\ \Rightarrow 3 = m.{\left( { - 2} \right)^2} - 2m.\left( { - 2} \right) - 3m - 2\\ \Leftrightarrow 3 = 4m + 4m - 3m - 2 \Leftrightarrow 5 = 5m \Leftrightarrow m = 1\\ b)\,\left( P \right)\,cat\,Ox\,tai\,B\left( {2;0} \right) \Rightarrow \left\{ \begin{array}{l} x = 2\\ y = 0 \end{array} \right.\\ \Rightarrow 0 = m{.2^2} - 2m.2 - 3m - 2 \Leftrightarrow 0 = 4m - 4m - 3m - 2\\ \Leftrightarrow - 3m - 2 = 0 \Leftrightarrow m = - \frac{2}{3}\\ c) - \frac{b}{{2a}} = - \frac{{ - 2m}}{m} = 2 \Rightarrow - \frac{\Delta }{{4a}} = - 3m - 2\\ \Rightarrow Dinh\,P\left( {2; - 3m - 2} \right) \in d \Leftrightarrow - 3m - 2 = 3.2 - 1 \Leftrightarrow - 3m = 7 \Leftrightarrow m = - \frac{7}{3} \end{array}$
