Tohaina
Kua tāruatia ki te papatopenga
6\left(-\frac{9}{4}\right)\leq u
Me whakarea ngā taha e rua ki te -\frac{9}{4}, te tau utu o -\frac{4}{9}. I te mea he tōraro a -\frac{4}{9}, ka huri te ahunga koreōrite.
\frac{6\left(-9\right)}{4}\leq u
Tuhia te 6\left(-\frac{9}{4}\right) hei hautanga kotahi.
\frac{-54}{4}\leq u
Whakareatia te 6 ki te -9, ka -54.
-\frac{27}{2}\leq u
Whakahekea te hautanga \frac{-54}{4} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 2.
u\geq -\frac{27}{2}
Whakawhitihia ngā taha kia puta ki te taha mauī ngā kīanga tau taurangi katoa. Ka huri tēnei i te aronga o te tohu.
