Kua tāruatia ki te papatopenga
4x-16=\left(x-4\right)\times 4
Tē taea kia ōrite te tāupe x ki 4 nā te kore tautuhi i te whakawehenga mā te kore. Me whakarea ngā taha e rua o te whārite ki te \left(x-4\right)^{2}, arā, te tauraro pātahi he tino iti rawa te kitea o x^{2}-8x+16,x-4.
4x-16=4x-16
Whakamahia te āhuatanga tohatoha hei whakarea te x-4 ki te 4.
4x-16-4x=-16
Tangohia te 4x mai i ngā taha e rua.
-16=-16
Pahekotia te 4x me -4x, ka 0.
\text{true}
Whakatauritea te -16 me te -16.
x\in \mathrm{R}
He pono tēnei mō tētahi x ahakoa.
x\in \mathrm{R}\setminus 4
Tē taea kia ōrite te tāupe x ki 4.
