5 raruraru e ōrite ana ki:
\frac { 3 - x } { x + 5 } \leq 0 \quad \frac { x + 1 } { x - 1 }
Tohaina
Kua tāruatia ki te papatopenga
\frac{3-x}{x+5}\leq 0
Ko te tau i whakarea ki te kore ka hua ko te kore.
3-x\geq 0 x+5<0
Kia ≤0 rawa te otinga, hei ≥0 tonu tētahi o ngā uara o 3-x me x+5, hei ≤0 anō tērā atu, otiia tē taea ai hei kore te x+5. Whakaarohia te tauira ina tōraro tahi a 3-x\geq 0 me x+5.
x<-5
Te otinga e whakaea i ngā koreōrite e rua ko x<-5.
3-x\leq 0 x+5>0
Whakaarohia te tauira ina tōrunga tahi a 3-x\leq 0 me x+5.
x\geq 3
Te otinga e whakaea i ngā koreōrite e rua ko x\geq 3.
x<-5\text{; }x\geq 3
Ko te otinga whakamutunga ko te whakakotahi i ngā otinga kua whiwhi.
