Kua tāruatia ki te papatopenga
3x-4x^{2}<0
Tangohia te 4x^{2} mai i ngā taha e rua.
-3x+4x^{2}>0
Me whakarea te koreōrite ki te -1 kia tōrunga ai te tau whakarea o te pū tino teitei i 3x-4x^{2}. I te mea he tōraro a -1, ka huri te ahunga koreōrite.
x\left(4x-3\right)>0
Tauwehea te x.
x<0 x-\frac{3}{4}<0
Kia tōrunga te otinga, me tōraro tahi te x me te x-\frac{3}{4}, me tōrunga tahi rānei. Whakaarohia te tauira ina he tōraro tahi te x me te x-\frac{3}{4}.
x<0
Te otinga e whakaea i ngā koreōrite e rua ko x<0.
x-\frac{3}{4}>0 x>0
Whakaarohia te tauira ina he tōrunga tahi te x me te x-\frac{3}{4}.
x>\frac{3}{4}
Te otinga e whakaea i ngā koreōrite e rua ko x>\frac{3}{4}.
x<0\text{; }x>\frac{3}{4}
Ko te otinga whakamutunga ko te whakakotahi i ngā otinga kua whiwhi.
