Réitigh xθ^2+yθ+z=0

$$x { \theta }^{ 2 } +y \theta +z=0$$

Réitigh do x. (complex solution)

$$\left\{\begin{matrix}x=-\frac{y\theta +z}{\theta ^{2}}\text{, }&\theta \neq 0\\x\in \mathrm{C}\text{, }&z=0\text{ and }\theta =0\end{matrix}\right.$$

Céimeanna chun Cothromóidí Líneacha a Réiteach

Bain y\theta ón dá thaobh. Is ionann rud ar bith a dhealaítear ó nialas agus a shéanadh.

$$x\theta ^{2}+z=-y\theta$$

Bain z ón dá thaobh.

$$x\theta ^{2}=-y\theta -z$$

Tá an chothromóid i bhfoirm chaighdeánach.

$$\theta ^{2}x=-y\theta -z$$

Roinn an dá thaobh faoi \theta ^{2}.

$$\frac{\theta ^{2}x}{\theta ^{2}}=\frac{-y\theta -z}{\theta ^{2}}$$

Má roinntear é faoi \theta ^{2} cuirtear an iolrúchán faoi \theta ^{2} ar ceal.

$$x=\frac{-y\theta -z}{\theta ^{2}}$$

Roinn -y\theta -z faoi \theta ^{2}.

$$x=-\frac{y\theta +z}{\theta ^{2}}$$

Réitigh do y. (complex solution)

$$\left\{\begin{matrix}y=-x\theta -\frac{z}{\theta }\text{, }&\theta \neq 0\\y\in \mathrm{C}\text{, }&z=0\text{ and }\theta =0\end{matrix}\right.$$

Céimeanna chun Cothromóidí Líneacha a Réiteach

Bain x\theta ^{2} ón dá thaobh. Is ionann rud ar bith a dhealaítear ó nialas agus a shéanadh.

$$y\theta +z=-x\theta ^{2}$$

Bain z ón dá thaobh.

$$y\theta =-x\theta ^{2}-z$$

Tá an chothromóid i bhfoirm chaighdeánach.

$$\theta y=-x\theta ^{2}-z$$

Roinn an dá thaobh faoi \theta .

$$\frac{\theta y}{\theta }=\frac{-x\theta ^{2}-z}{\theta }$$

Má roinntear é faoi \theta cuirtear an iolrúchán faoi \theta ar ceal.
