Whakaoti i te x*(x+2)=x*(x+3)

$$x \times (x+2)=x \times (x+3)$$

Whakaoti mō x

$$x=0$$

Ngā Upane mō te Whakaoti Whārite Rārangi

Whakamahia te āhuatanga tohatoha hei whakarea te x ki te x+2.

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

Whakamahia te āhuatanga tohatoha hei whakarea te x ki te x+3.

$$x^{2}+2x=x^{2}+3x$$

Tangohia te x^{2} mai i ngā taha e rua.

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

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

$$2x=3x$$

Tangohia te 3x mai i ngā taha e rua.

$$2x-3x=0$$

Pahekotia te 2x me -3x, ka -x.

$$-x=0$$

He ōrite te hua o ngā tau e rua ki 0 ina 0 tētahi o rāua te iti rawa. Tātemea kāore te -1 e ōrite ki 0, me ōrite pū te x ki 0.

$$x=0$$
