Respuesta:
10m²5mn-5n
Explicación paso a paso:
(4m²-2mn-5n)+(6m²+7mn)
Sumas los monomios comunes y coloco el que sobra
4m²+6m²=10m²
-2mn+7mn=5mn
[tex]\mathrm{\left(4m^2-2mn-5n\right)+\left(6m^2+7mn\right)}[/tex]
[tex]\mathrm{4m^2-2mn-5n+6m^2+7mn}[/tex]
[tex]\mathrm{4m^2+6m^2-2mn+7mn-5n}[/tex]
[tex]\mathrm{4m^2+6m^2=10m^2}[/tex]
[tex]\mathrm{-2mn+7mn=5mn}[/tex]
