Tohaina
Kua tāruatia ki te papatopenga
x-\left(-4\right)=6
Whakaarohia te whārite tuatahi. Me kōkuhu ngā uara tāupe mōhiotia ki te whārite.
x+4=6
Whakareatia te -1 ki te -4, ka 4.
x=6-4
Tangohia te 4 mai i ngā taha e rua.
x=2
Tangohia te 4 i te 6, ka 2.
x=2 y=-4
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
