Kua tāruatia ki te papatopenga
3\left(ac-ad-2bc+2bd\right)
Tauwehea te 3.
a\left(c-d\right)-2b\left(c-d\right)
Whakaarohia te ac-ad-2bc+2bd. Mahia te whakarōpūtanga ac-ad-2bc+2bd=\left(ac-ad\right)+\left(-2bc+2bd\right), ka whakatauwehea atu a i te tuatahi me -2b i te rōpū tuarua.
\left(c-d\right)\left(a-2b\right)
Whakatauwehea atu te kīanga pātahi c-d mā te whakamahi i te āhuatanga tātai tohatoha.
3\left(c-d\right)\left(a-2b\right)
Me tuhi anō te kīanga whakatauwehe katoa.
