\left(-x\right)\left(x^{2}-4x+4\right)
Whakamahia te ture huarua \left(a-b\right)^{2}=a^{2}-2ab+b^{2} hei whakaroha \left(x-2\right)^{2}.
\left(-x\right)x^{2}-4\left(-x\right)x+4\left(-x\right)
Whakamahia te āhuatanga tohatoha hei whakarea te -x ki te x^{2}-4x+4.
\left(-x\right)x^{2}+4xx+4\left(-x\right)
Whakareatia te -4 ki te -1, ka 4.
\left(-x\right)x^{2}+4x^{2}+4\left(-x\right)
Whakareatia te x ki te x, ka x^{2}.
-x^{3}+4x^{2}+4\left(-1\right)x
Hei whakarea i ngā pū o te pūtake kotahi, me tāpiri ō rātou taupū. Tāpiria te 1 me te 2 kia riro ai te 3.
-x^{3}+4x^{2}-4x
Whakareatia te 4 ki te -1, ka -4.
\left(-x\right)\left(x^{2}-4x+4\right)
Whakamahia te ture huarua \left(a-b\right)^{2}=a^{2}-2ab+b^{2} hei whakaroha \left(x-2\right)^{2}.
\left(-x\right)x^{2}-4\left(-x\right)x+4\left(-x\right)

\left(-x\right)x^{2}+4xx+4\left(-x\right)
Whakareatia te -4 ki te -1, ka 4.
\left(-x\right)x^{2}+4x^{2}+4\left(-x\right)
Whakareatia te x ki te x, ka x^{2}.
-x^{3}+4x^{2}+4\left(-1\right)x
Hei whakarea i ngā pū o te pūtake kotahi, me tāpiri ō rātou taupū. Tāpiria te 1 me te 2 kia riro ai te 3.
-x^{3}+4x^{2}-4x
Whakareatia te 4 ki te -1, ka -4.
