\left(x+2\right)\left(x^{2}-2x+1\right)
Tā te Rational Root Theorem, ko ngā pūtake whakahau katoa o tētahi pūrau kei te āhua o \frac{p}{q}, ina wehea e p te kīanga pūmau 2, ā, ka wehea e q te whakarea arahanga 1. Ko tetahi pūtake pērā ko -2. Tauwehea te pūrau mā te whakawehe mā te x+2.
\left(x-1\right)^{2}
Whakaarohia te x^{2}-2x+1. Whakamahia te tikanga tātai pūrua pā, a^{2}-2ab+b^{2}=\left(a-b\right)^{2}, ina a=x, ina b=1.
\left(x+2\right)\left(x-1\right)^{2}
Me tuhi anō te kīanga whakatauwehe katoa.
