-2x-4<0 x-1<0
Kia tōrunga te otinga, me tōraro tahi te -2x-4 me te x-1, me tōrunga tahi rānei. Whakaarohia te tauira ina he tōraro tahi te -2x-4 me te x-1.
x\in \left(-2,1\right)
Te otinga e whakaea i ngā koreōrite e rua ko x\in \left(-2,1\right).
x-1>0 -2x-4>0
Whakaarohia te tauira ina he tōrunga tahi te -2x-4 me te x-1.
x\in \emptyset
He teka tēnei mō tētahi x ahakoa.
x\in \left(-2,1\right)
Ko te otinga whakamutunga ko te whakakotahi i ngā otinga kua whiwhi.
