x+2<0 x-3<0
Kia tōrunga te otinga, me tōraro tahi te x+2 me te x-3, me tōrunga tahi rānei. Whakaarohia te tauira ina he tōraro tahi te x+2 me te x-3.
x<-2
Te otinga e whakaea i ngā koreōrite e rua ko x<-2.
x-3>0 x+2>0
Whakaarohia te tauira ina he tōrunga tahi te x+2 me te x-3.
x>3
Te otinga e whakaea i ngā koreōrite e rua ko x>3.
x<-2\text{; }x>3
Ko te otinga whakamutunga ko te whakakotahi i ngā otinga kua whiwhi.
