Kua tāruatia ki te papatopenga
x\left(x+5\right)>0
Tauwehea te x.
x+5<0 x<0
Kia tōrunga te otinga, me tōraro tahi te x+5 me te x, me tōrunga tahi rānei. Whakaarohia te tauira ina he tōraro tahi te x+5 me te x.
x<-5
Te otinga e whakaea i ngā koreōrite e rua ko x<-5.
x>0 x+5>0
Whakaarohia te tauira ina he tōrunga tahi te x+5 me te x.
x>0
Te otinga e whakaea i ngā koreōrite e rua ko x>0.
x<-5\text{; }x>0
Ko te otinga whakamutunga ko te whakakotahi i ngā otinga kua whiwhi.
