Kua tāruatia ki te papatopenga
x+3\geq 0 x-2\leq 0
Kia ≤0 te otinga, me ≥0 rawa tētahi uara o x+3 me x-2, me ≤0 anō te uara o tētahi. Whakaarohia te tauira ina ko x+3\geq 0 me x-2\leq 0.
x\in \begin{bmatrix}-3,2\end{bmatrix}
Te otinga e whakaea i ngā koreōrite e rua ko x\in \left[-3,2\right].
x-2\geq 0 x+3\leq 0
Whakaarohia te tauira ina ko x+3\leq 0 me x-2\geq 0.
x\in \emptyset
He teka tēnei mō tētahi x ahakoa.
x\in \begin{bmatrix}-3,2\end{bmatrix}
Ko te otinga whakamutunga ko te whakakotahi i ngā otinga kua whiwhi.
