Me hoatu te āhuatanga tohatoha mā te whakarea ia tau o x+2 ki ia tau o x-1.

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

Pahekotia te -x me 2x, ka x.

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

Me hoatu te āhuatanga tohatoha mā te whakarea ia tau o x^{2}+x-2 ki ia tau o x+1.

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

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

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

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

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

Me hoatu te āhuatanga tohatoha mā te whakarea ia tau o x^{3}+2x^{2}-x-2 ki ia tau o 3x+1.

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

Pahekotia te x^{3} me 6x^{3}, ka 7x^{3}.

$$3x^{4}+7x^{3}+2x^{2}-3x^{2}-x-6x-2$$

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

$$3x^{4}+7x^{3}-x^{2}-x-6x-2$$

Pahekotia te -x me -6x, ka -7x.

$$3x^{4}+7x^{3}-x^{2}-7x-2$$

Whakaroha
