Whakaoti mō y, x
x=4
y=-1
Tohaina
Kua tāruatia ki te papatopenga
y=\frac{-1}{\sqrt{1}}
Whakaarohia te whārite tuatahi. Tātaihia te i mā te pū o 2, kia riro ko -1.
y=\frac{-1}{1}
Tātaitia te pūtakerua o 1 kia tae ki 1.
y=-1
Ka whakawehea he tau ki te tahi, hua ai ko ia anō.
y=-1 x=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
whārite paerangi
y = 3x + 4
