porfa ayuda (1/2m3 - 2/3m2) + (2/5m3 + 1/6m2) suma de polinomios

Answer 1

$= (\frac{1}{2} {m}^{3} - \frac{2}{3} {m}^{2} ) + ( \frac{2}{5} {m}^{3} + \frac{1}{6} {m}^{2} ) \\ = ( \frac{1}{2} {m}^{3} + \frac{2}{5} {m}^{3} ) + ( \frac{1}{6} {m}^{2} - \frac{2}{3} {m}^{2} ) \\ = \frac{5 {m}^{3} + 4 {m}^{3} }{10} + \frac{ {m}^{2} - 4 {m}^{2} }{6} \\ = \frac{9}{10 }{m}^{3} - \frac{3}{6} {m}^{2} \\ = \frac{9}{10 } {m}^{3} - \frac{1}{2} {m}^{2}$
