Whakaoti i te x(x+3)+3x+3-x(x-3)-3(x-3)

$$x ( x + 3 ) + 3 x + 3 - x ( x - 3 ) - 3 ( x - 3 )$$

Aromātai

$$6\left(x+2\right)$$

Ngā Upane Otinga

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

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

Pahekotia te 3x me 3x, ka 6x.

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

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

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

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

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

Ko te tauaro o -3x ko 3x.

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

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

$$6x+3+3x-3\left(x-3\right)$$

Pahekotia te 6x me 3x, ka 9x.

$$9x+3-3\left(x-3\right)$$

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

$$9x+3-3x+9$$

Pahekotia te 9x me -3x, ka 6x.

$$6x+3+9$$

Tāpirihia te 3 ki te 9, ka 12.

$$6x+12$$

Whakaroha
