Whakaoti i te x(x+2)(x+2)+2(x+2)(x-2)

$$x ( x + 2 ) ( x + 2 ) + 2 ( x + 2 ) ( x - 2 )$$

Aromātai

$$\left(x+2\right)\left(x\left(x+4\right)-4\right)$$

Ngā Upane Otinga

Whakareatia te x+2 ki te x+2, ka \left(x+2\right)^{2}.

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

Whakamahia te ture huarua \left(a+b\right)^{2}=a^{2}+2ab+b^{2} hei whakaroha \left(x+2\right)^{2}.

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

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

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

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

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

Me hoatu te āhuatanga tohatoha mā te whakarea ia tau o 2x+4 ki ia tau o x-2.

$$x^{3}+4x^{2}+4x+2x^{2}-4x+4x-8$$

Pahekotia te -4x me 4x, ka 0.

$$x^{3}+4x^{2}+4x+2x^{2}-8$$

Pahekotia te 4x^{2} me 2x^{2}, ka 6x^{2}.

$$x^{3}+6x^{2}+4x-8$$

Whakaroha

$$x^{3}+6x^{2}+4x-8$$
