ĐKXĐ: \(x \ne \dfrac{1}{2};x \ne -5\)
\( Pt \Leftrightarrow \left( {2x + 3} \right)\left( {x + 5} \right) = \left( {x - 3} \right)\left( {2x - 1} \right)\\ \Leftrightarrow 2{x^2} + 10x + 3x + 15 = 2{x^2} - x - 6x + 3\\ \Leftrightarrow 13x + 15 = - 7x + 3\\ \Leftrightarrow 20x = - 12\\ \Leftrightarrow x = - \dfrac{3}{5}\left( {tm} \right) \)
