Explicación paso a paso:

$\frac{1}{2} {x}^{2} \times \frac{2}{3} x - \frac{1}{2} {x}^{2} \times \frac{3}{2} y - \frac{1}{3} xy \times \frac{2}{3} x + \frac{1}{3} xy \times \frac{3}{2} y + \frac{1}{4} {y}^{2} \times \frac{2}{3} x - \frac{1}{4} {y}^{2} \times \frac{3}{2} y = \\ \\ \frac{2}{6} {x}^{3 } - \frac{3}{4} {x}^{2} y - \frac{2}{6} {x}^{2} y + \frac{3}{6} x {y}^{2} + \frac{2}{12} x {y}^{2} - \frac{3}{8} {y}^{3} = \\ \\ \frac{2}{6} {x}^{3} - \frac{9 + 4}{12} {x}^{2} y + \frac{6 + 2}{12} x {y}^{2} - \frac{3}{8} {y}^{3} = \\ \\ \frac{2}{6} {x}^{3} - \frac{13}{12} {x}^{2} y + \frac{8}{12} x {y}^{2} - \frac{3}{8} {y}^{3} = \\ \\ \frac{2}{6} {x}^{3} - \frac{13}{12} {x}^{2} y + \frac{1}{3} x {y}^{2} - \frac{3}{8} {y}^{3}$
