Kua tāruatia ki te papatopenga
x^{2}-2x>0
Tangohia te 2x mai i ngā taha e rua.
x\left(x-2\right)>0
Tauwehea te x.
x<0 x-2<0
Kia tōrunga te otinga, me tōraro tahi te x me te x-2, me tōrunga tahi rānei. Whakaarohia te tauira ina he tōraro tahi te x me te x-2.
x<0
Te otinga e whakaea i ngā koreōrite e rua ko x<0.
x-2>0 x>0
Whakaarohia te tauira ina he tōrunga tahi te x me te x-2.
x>2
Te otinga e whakaea i ngā koreōrite e rua ko x>2.
x<0\text{; }x>2
Ko te otinga whakamutunga ko te whakakotahi i ngā otinga kua whiwhi.
