Kua tāruatia ki te papatopenga
6x^{2}-12=2x\left(3x-4\right)
Tē taea kia ōrite te tāupe x ki \frac{4}{3} nā te kore tautuhi i te whakawehenga mā te kore. Whakareatia ngā taha e rua o te whārite ki te 3x-4.
6x^{2}-12=6x^{2}-8x
Whakamahia te āhuatanga tohatoha hei whakarea te 2x ki te 3x-4.
6x^{2}-12-6x^{2}=-8x
Tangohia te 6x^{2} mai i ngā taha e rua.
-12=-8x
Pahekotia te 6x^{2} me -6x^{2}, ka 0.
-8x=-12
Whakawhitihia ngā taha kia puta ki te taha mauī ngā kīanga tau taurangi katoa.
x=\frac{-12}{-8}
Whakawehea ngā taha e rua ki te -8.
x=\frac{3}{2}
Whakahekea te hautanga \frac{-12}{-8} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te -4.
