resta de polinomios

Answer 1

Respuesta:

Resta de polinomios

A)

$(5mn^2 - 14m^2n + 17m^3)-(8mn^2 - 6m^2n - 12m^3)\\\\5mn^2 - 14m^2n + 17m^3 - 8mn^2 + 6m^2n+12m^3\\\\-3mn^2 - 8m^2n + 29m^3\\\\29m^3 - 3mn^2 - 8m^2n$

B)

$(5ab^2 - 7a^2b^3 - 8a^3b^4)-(2ab - 3a^2b^3 - 2a^3b^4)\\\\5ab^2 - 7a^2b^3 - 8a^3b^4 - 2ab + 3a^2b^3 + 2a^3b^4\\\\5ab^2 - 4a^2b^3 - 6a^3b^4 - 2ab$
