Whakaoti i te x(x^2-1)+x^2(x+2)-x(5-x^2)

$$x ( x ^ { 2 } - 1 ) + x ^ { 2 } ( x + 2 ) - x ( 5 - x ^ { 2 } )$$

Aromātai

$$x\left(3x^{2}+2x-6\right)$$

Ngā Upane Otinga

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

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

Whakamahia te āhuatanga tohatoha hei whakarea te x^{2} ki te x+2.

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

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

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

Whakamahia te āhuatanga tohatoha hei whakarea te x ki te 5-x^{2}.

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

Hei kimi i te tauaro o 5x-x^{3}, kimihia te tauaro o ia taurangi.

$$2x^{3}-x+2x^{2}-5x+x^{3}$$

Pahekotia te -x me -5x, ka -6x.

$$2x^{3}-6x+2x^{2}+x^{3}$$

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

$$3x^{3}-6x+2x^{2}$$

Whakaroha
