Ngā Upane Otinga

Whakamahia te āhuatanga tuaritanga hei whakarea te m^{2}+m+1 ki te m+1 ka whakakotahi i ngā kupu rite.

$$m^{3}+2m^{2}+2m+1+\left(m^{2}-m-1\right)\left(m-1\right)-2m\left(m^{2}+1\right)$$

Whakamahia te āhuatanga tuaritanga hei whakarea te m^{2}-m-1 ki te m-1 ka whakakotahi i ngā kupu rite.

$$m^{3}+2m^{2}+2m+1+m^{3}-2m^{2}+1-2m\left(m^{2}+1\right)$$

Pahekotia te m^{3} me m^{3}, ka 2m^{3}.

$$2m^{3}+2m^{2}+2m+1-2m^{2}+1-2m\left(m^{2}+1\right)$$

Pahekotia te 2m^{2} me -2m^{2}, ka 0.

$$2m^{3}+2m+1+1-2m\left(m^{2}+1\right)$$

Tāpirihia te 1 ki te 1, ka 2.

$$2m^{3}+2m+2-2m\left(m^{2}+1\right)$$

Whakamahia te āhuatanga tohatoha hei whakarea te -2m ki te m^{2}+1.

$$2m^{3}+2m+2-2m^{3}-2m$$

Pahekotia te 2m^{3} me -2m^{3}, ka 0.

$$2m+2-2m$$

Pahekotia te 2m me -2m, ka 0.
