x^{2}\left(x-4\right)-25\left(x-4\right)
Mahia te whakarōpūtanga x^{3}-4x^{2}-25x+100=\left(x^{3}-4x^{2}\right)+\left(-25x+100\right), ka whakatauwehea atu x^{2} i te tuatahi me -25 i te rōpū tuarua.
\left(x-4\right)\left(x^{2}-25\right)
Whakatauwehea atu te kīanga pātahi x-4 mā te whakamahi i te āhuatanga tātai tohatoha.
\left(x-5\right)\left(x+5\right)
Whakaarohia te x^{2}-25. Tuhia anō te x^{2}-25 hei x^{2}-5^{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-5\right)\left(x-4\right)\left(x+5\right)
Me tuhi anō te kīanga whakatauwehe katoa.
