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 -12, ā, ka wehea e q te whakarea arahanga 1. Ko tetahi pūtake pērā ko 3. Tauwehea te pūrau mā te whakawehe mā te x-3.
\left(x+2\right)^{2}
Whakaarohia te x^{2}+4x+4. Whakamahia te tikanga tātai pūrua pā, a^{2}+2ab+b^{2}=\left(a+b\right)^{2}, ina a=x, ina b=2.
\left(x-3\right)\left(x+2\right)^{2}
Me tuhi anō te kīanga whakatauwehe katoa.
