A. \(\left[ \begin{array}{l}x = 0\\x = \dfrac{2}{3}\end{array} \right.\)
B. \(\left[ \begin{array}{l}x = 0\\x = \dfrac{3}{2}\end{array} \right.\)
C. \(\left[ \begin{array}{l}x = 0\\x = - \dfrac{3}{2}\end{array} \right.\)
D. \(\left[ \begin{array}{l}x = 0\\x = - \dfrac{2}{3}\end{array} \right.\)
C
\(\begin{array}{l}\;2{x^2} + 3x = 0\\ \Leftrightarrow x\left( {2x + 3} \right) = 0\\ \Leftrightarrow \left[ \begin{array}{l}x = 0\\2x + 3 = 0\end{array} \right.\\ \Leftrightarrow \left[ \begin{array}{l}x = 0\\x = - \dfrac{3}{2}\end{array} \right.\end{array}\)
