Whakaoti mō q
\left\{\begin{matrix}q=-\frac{x-r}{y}\text{, }&y\neq 0\\q\in \mathrm{R}\text{, }&x=r\text{ and }y=0\end{matrix}\right.
Whakaoti mō r
r=x+qy
Tohaina
Kua tāruatia ki te papatopenga
qy=r-x
Tangohia te x mai i ngā taha e rua.
yq=r-x
He hanga arowhānui tō te whārite.
\frac{yq}{y}=\frac{r-x}{y}
Whakawehea ngā taha e rua ki te y.
q=\frac{r-x}{y}
Mā te whakawehe ki te y ka wetekia te whakareanga ki te y.
r=x+qy
Whakawhitihia ngā taha kia puta ki te taha mauī ngā kīanga tau taurangi katoa.
Ngā Tauira
whārite tapawhā
{ x } ^ { 2 } - 4 x - 5 = 0
Āhuahanga
4 \sin \theta \cos \theta = 2 \sin \theta
