Whakaoti i te (5m-m)^2-(m+n)^2

$$( 5 m - m ) ^ { 2 } - ( m + n ) ^ { 2 }$$

Aromātai

$$\left(3m-n\right)\left(5m+n\right)$$

Ngā Upane Otinga

Pahekotia te 5m me -m, ka 4m.

$$\left(4m\right)^{2}-\left(m+n\right)^{2}$$

Whakarohaina te \left(4m\right)^{2}.

$$4^{2}m^{2}-\left(m+n\right)^{2}$$

Tātaihia te 4 mā te pū o 2, kia riro ko 16.

$$16m^{2}-\left(m+n\right)^{2}$$

Whakamahia te ture huarua \left(a+b\right)^{2}=a^{2}+2ab+b^{2} hei whakaroha \left(m+n\right)^{2}.

$$16m^{2}-\left(m^{2}+2mn+n^{2}\right)$$

Hei kimi i te tauaro o m^{2}+2mn+n^{2}, kimihia te tauaro o ia taurangi.

$$16m^{2}-m^{2}-2mn-n^{2}$$

Pahekotia te 16m^{2} me -m^{2}, ka 15m^{2}.

$$15m^{2}-2mn-n^{2}$$

Whakaroha

$$15m^{2}-2mn-n^{2}$$
