m^{2}-3^{2}-m\left(m+2\right)
Whakaarohia te \left(m-3\right)\left(m+3\right). Ka taea te whakareanga te panoni ki te rerekētanga o ngā pūrua mā te ture: \left(a-b\right)\left(a+b\right)=a^{2}-b^{2}.
m^{2}-9-m\left(m+2\right)
Tātaihia te 3 mā te pū o 2, kia riro ko 9.
m^{2}-9-\left(m^{2}+2m\right)
Whakamahia te āhuatanga tohatoha hei whakarea te m ki te m+2.
m^{2}-9-m^{2}-2m
Hei kimi i te tauaro o m^{2}+2m, kimihia te tauaro o ia taurangi.
-9-2m
Pahekotia te m^{2} me -m^{2}, ka 0.
m^{2}-3^{2}-m\left(m+2\right)
Whakaarohia te \left(m-3\right)\left(m+3\right). Ka taea te whakareanga te panoni ki te rerekētanga o ngā pūrua mā te ture: \left(a-b\right)\left(a+b\right)=a^{2}-b^{2}.
m^{2}-9-m\left(m+2\right)
Tātaihia te 3 mā te pū o 2, kia riro ko 9.
m^{2}-9-\left(m^{2}+2m\right)
Whakamahia te āhuatanga tohatoha hei whakarea te m ki te m+2.
m^{2}-9-m^{2}-2m
Hei kimi i te tauaro o m^{2}+2m, kimihia te tauaro o ia taurangi.
-9-2m
Pahekotia te m^{2} me -m^{2}, ka 0.
