Kua tāruatia ki te papatopenga
2x^{3}+x^{2}-2x-1
Whakarea ka paheko i ngā kīanga tau ōrite.
x^{2}\left(2x+1\right)-\left(2x+1\right)
Mahia te whakarōpūtanga 2x^{3}+x^{2}-2x-1=\left(2x^{3}+x^{2}\right)+\left(-2x-1\right), ka whakatauwehea atu x^{2} i te tuatahi me -1 i te rōpū tuarua.
\left(2x+1\right)\left(x^{2}-1\right)
Whakatauwehea atu te kīanga pātahi 2x+1 mā te whakamahi i te āhuatanga tātai tohatoha.
\left(x-1\right)\left(x+1\right)
Whakaarohia te x^{2}-1. Tuhia anō te x^{2}-1 hei x^{2}-1^{2}. Ka taea te rerekētanga o ngā pūrua te whakatauwehe mā te ture: a^{2}-b^{2}=\left(a-b\right)\left(a+b\right).
\left(x-1\right)\left(x+1\right)\left(2x+1\right)
Me tuhi anō te kīanga whakatauwehe katoa.
2x^{3}-2x-1+x^{2}
Pahekotia te x me -3x, ka -2x.
