RESUELVE LA SIGUIENTE OPERACION [(7m^2+3mn+6n^2 )+(-5m^3+5mn+6m^2-n^2 )]-[(7m^2+3mn+6n^2 )-(6m^3+4mn-2n^2+m^2 )]

Answer 1

Explicación paso a paso:

[(7m^2+3mn+6n^2 )+(-5m^3+5mn+6m^2-n^2 )]-[(7m^2+3mn+6n^2 )-(6m^3+4mn-2n^2+m^2 )]

=7m2+3mn+6n2−5m3+5mn+6m2−n2−1(7m2+3mn+6n2−(6m3+4mn−2n2+m2))

=7m2+3mn+6n2+−5m3+5mn+6m2+−n2+−1(7m2)+−1(3mn)+−1(6n2)+−1(−6m3)+−1(−4mn)+−1(2n2)+−1(−m2)

=7m2+3mn+6n2+−5m3+5mn+6m2+−n2+−7m2+−3mn+−6n2+6m3+4mn+−2n2+m2

=(−5m3+6m3)+(7m2+6m2+−7m2+m2)+(3mn+5mn+−3mn+4mn)+(6n2+−n2+−6n2+−2n2)

=m3+7m2+9mn+−3n2

Listo cariñoo!
