x^{2}-2x<0
Tangohia te 2x mai i ngā taha e rua.
x\left(x-2\right)<0
Tauwehea te x.
x>0 x-2<0
Kia tōraro te otinga, me tauaro rawa ngā tohu o te x me te x-2. Whakaarohia te tauira ina he tōrunga te x he tōraro te x-2.
x\in \left(0,2\right)
Te otinga e whakaea i ngā koreōrite e rua ko x\in \left(0,2\right).
x-2>0 x<0
Whakaarohia te tauira ina he tōrunga te x-2 he tōraro te x.
x\in \emptyset
He teka tēnei mō tētahi x ahakoa.
x\in \left(0,2\right)
Ko te otinga whakamutunga ko te whakakotahi i ngā otinga kua whiwhi.
