Explicación paso a paso:
(3x²)(9xy)= 3•9•x²•x•y = 27 x³y
(-2ab²)(5a²b + 10c – 5)
= (-2ab²)(5a²b) + (-2ab²)(10c) + (-2ab²)(-5)
= -10a³b³ – 20ab²c + 10ab²
con factor común:
= 10ab²(-1a²b – 2c + 1)
(14m + 10)(12m²n + 2n)
= (14m + 10)(12m²n) + (14m + 10)(2n)
= (12m²n)(14m) + (12m²n)(10) + (2n)(14m) + (2n)(10)
= 168m³n + 120m²n + 28mn + 20n
= 4n(42m³ + 30m² + 7m + 5)
Espero sea de tu ayuda. ¡Éxitos!
