9x^{2}-12x+4=9x^{2}-12x+4
Whakamahia te ture huarua \left(a-b\right)^{2}=a^{2}-2ab+b^{2} hei whakaroha \left(3x-2\right)^{2}.
9x^{2}-12x+4-9x^{2}=-12x+4
Tangohia te 9x^{2} mai i ngā taha e rua.
-12x+4=-12x+4
Pahekotia te 9x^{2} me -9x^{2}, ka 0.
-12x+4+12x=4
Me tāpiri te 12x ki ngā taha e rua.
4=4
Pahekotia te -12x me 12x, ka 0.
\text{true}
Whakatauritea te 4 me te 4.
x\in \mathrm{C}
He pono tēnei mō tētahi x ahakoa.
