3x^{2}-6x=2x\left(x-3\right)
Whakamahia te āhuatanga tohatoha hei whakarea te 3x ki te x-2.
3x^{2}-6x=2x^{2}-6x
Whakamahia te āhuatanga tohatoha hei whakarea te 2x ki te x-3.
3x^{2}-6x-2x^{2}=-6x
Tangohia te 2x^{2} mai i ngā taha e rua.
x^{2}-6x=-6x
Pahekotia te 3x^{2} me -2x^{2}, ka x^{2}.
x^{2}-6x+6x=0
Me tāpiri te 6x ki ngā taha e rua.
x^{2}=0
Pahekotia te -6x me 6x, ka 0.
x=0 x=0
Tuhia te pūtakerua o ngā taha e rua o te whārite.
x=0
Kua oti te whārite te whakatau. He ōrite ngā whakatau.

x=\frac{0±\sqrt{0^{2}}}{2}
Kei te āhua arowhānui tēnei whārite: ax^{2}+bx+c=0. Me whakakapi 1 mō a, 0 mō b, me 0 mō c i te tikanga tātai pūrua, \frac{-b±\sqrt{b^{2}-4ac}}{2a}.
x=\frac{0±0}{2}
Tuhia te pūtakerua o te 0^{2}.
x=0
Whakawehe 0 ki te 2.
