Graph
Tohaina
Kua tāruatia ki te papatopenga
3=-x-2
Whakaarohia te whārite tuatahi. Me kōkuhu ngā uara tāupe mōhiotia ki te whārite.
-x-2=3
Whakawhitihia ngā taha kia puta ki te taha mauī ngā kīanga tau taurangi katoa.
-x=3+2
Me tāpiri te 2 ki ngā taha e rua.
-x=5
Tāpirihia te 3 ki te 2, ka 5.
x=-5
Whakawehea ngā taha e rua ki te -1.
y=3 x=-5
Kua oti te pūnaha te whakatau.
Ngā Tauira
whārite tapawhā
{ x } ^ { 2 } - 4 x - 5 = 0
Āhuahanga
4 \sin \theta \cos \theta = 2 \sin \theta
