Question

{(m²-5m) - 1m² +8 m)} is​

Answer 1

$\rm{(m^{2} - 5m) - (1m^{2} + 8m)=m^{2} - 5m - 1m^{2} - 8m}$

$\longrightarrow\rm{(m^{2} - 5m) - (1m^{2} + 8m)=m^{2} - 1m^{2} - 5m - 8m}$

$\longrightarrow\rm{(m^{2} - 5m) - (1m^{2} + 8m)=m^{2} - m^{2} - 5m - 8m}$

$\longrightarrow\rm{(m^{2} - 5m) - (1m^{2} + 8m)=- 5m - 8m = -13 m}$
