Kua tāruatia ki te papatopenga
x\times 2=4\times 10
Tē taea kia ōrite te tāupe x ki 0 nā te kore tautuhi i te whakawehenga mā te kore. Me whakarea ngā taha e rua o te whārite ki te 4x, arā, te tauraro pātahi he tino iti rawa te kitea o 4,x.
x\times 2=40
Whakareatia te 4 ki te 10, ka 40.
x=\frac{40}{2}
Whakawehea ngā taha e rua ki te 2.
x=20
Whakawehea te 40 ki te 2, kia riro ko 20.
Ngā Tauira
whārite tapawhā
{ x } ^ { 2 } - 4 x - 5 = 0
Āhuahanga
