Kua tāruatia ki te papatopenga
x\left(3x+4\right)>0
Tauwehea te x.
x+\frac{4}{3}<0 x<0
Kia tōrunga te otinga, me tōraro tahi te x+\frac{4}{3} me te x, me tōrunga tahi rānei. Whakaarohia te tauira ina he tōraro tahi te x+\frac{4}{3} me te x.
x<-\frac{4}{3}
Te otinga e whakaea i ngā koreōrite e rua ko x<-\frac{4}{3}.
x>0 x+\frac{4}{3}>0
Whakaarohia te tauira ina he tōrunga tahi te x+\frac{4}{3} me te x.
x>0
Te otinga e whakaea i ngā koreōrite e rua ko x>0.
x<-\frac{4}{3}\text{; }x>0
Ko te otinga whakamutunga ko te whakakotahi i ngā otinga kua whiwhi.
