2-x>0 3-x<0
Kia tōraro te otinga, me tauaro rawa ngā tohu o te 2-x me te 3-x. Whakaarohia te tauira ina he tōrunga te 2-x he tōraro te 3-x.
x\in \emptyset
He teka tēnei mō tētahi x ahakoa.
3-x>0 2-x<0
Whakaarohia te tauira ina he tōrunga te 3-x he tōraro te 2-x.
x\in \left(2,3\right)
Te otinga e whakaea i ngā koreōrite e rua ko x\in \left(2,3\right).
x\in \left(2,3\right)
Ko te otinga whakamutunga ko te whakakotahi i ngā otinga kua whiwhi.
