Whakaoti i te 4a^2-4a[4-a(4-a+a^2)]

$$4 a ^ { 2 } - 4 a [ 4 - a ( 4 - a + a ^ { 2 } ) ]$$

Aromātai

$$4a\left(a^{3}-a^{2}+5a-4\right)$$

Ngā Upane Otinga

Whakamahia te āhuatanga tohatoha hei whakarea te a ki te 4-a+a^{2}.

$$4a^{2}-4a\left(4-\left(4a-a^{2}+a^{3}\right)\right)$$

Hei kimi i te tauaro o 4a-a^{2}+a^{3}, kimihia te tauaro o ia taurangi.

$$4a^{2}-4a\left(4-4a+a^{2}-a^{3}\right)$$

Whakamahia te āhuatanga tohatoha hei whakarea te -4a ki te 4-4a+a^{2}-a^{3}.

$$4a^{2}-16a+16a^{2}-4a^{3}+4a^{4}$$

Pahekotia te 4a^{2} me 16a^{2}, ka 20a^{2}.

$$20a^{2}-16a-4a^{3}+4a^{4}$$

Whakaroha

$$4a^{4}-4a^{3}+20a^{2}-16a$$

Ngā Upane Otinga

Whakamahia te āhuatanga tohatoha hei whakarea te a ki te 4-a+a^{2}.

$$4a^{2}-4a\left(4-\left(4a-a^{2}+a^{3}\right)\right)$$

Hei kimi i te tauaro o 4a-a^{2}+a^{3}, kimihia te tauaro o ia taurangi.

$$4a^{2}-4a\left(4-4a+a^{2}-a^{3}\right)$$

Whakamahia te āhuatanga tohatoha hei whakarea te -4a ki te 4-4a+a^{2}-a^{3}.

$$4a^{2}-16a+16a^{2}-4a^{3}+4a^{4}$$

Pahekotia te 4a^{2} me 16a^{2}, ka 20a^{2}.

$$20a^{2}-16a-4a^{3}+4a^{4}$$
