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

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

Whakamahia te āhuatanga tuaritanga hei whakarea te x^{3}-x^{2} ki te x+1 ka whakakotahi i ngā kupu rite.

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

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

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

Whakamahia te āhuatanga tuaritanga hei whakarea te x^{3}-2x^{2} ki te x+2 ka whakakotahi i ngā kupu rite.

$$x^{4}-x^{2}-\left(x^{4}-4x^{2}\right)$$

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

$$x^{4}-x^{2}-x^{4}+4x^{2}$$

Pahekotia te x^{4} me -x^{4}, ka 0.

$$-x^{2}+4x^{2}$$

Pahekotia te -x^{2} me 4x^{2}, ka 3x^{2}.
