Answer 1

Respuesta:

Explicación paso a paso:

1. (4m-6mn+8m²-7mn²)+(6mn²+12m-2m²)

=4m-6mn+8m²-7mn²+6mn²+12m-2m²

=-7mn²+6mn²+8m²-2m²+12m+4m-6mn

=mn²+6m²+16m-6mn

2. (6mn²+12m-2m²)+(14m²-7mn²+7m)

= 6mn²+12m-2m²+14m²-7mn²+7m

=6mn²-7mn²-2m²+14m²+12m+7m

=mn²+12m²+19m

3. (4m-6mn+8m²-7mn²)+(14m²-7mn²+7m)

(4m-6mn+8m²-7mn²)+(14m²-7mn²+7m)

-14mn²+22m²+-6mn+11m
