Datrys x2+sqrt{y}=1

$$x2+ \sqrt{ y } =1$$

Datrys ar gyfer y

$$y=\left(1-x_{2}\right)^{2}$$

$$1-x_{2}\geq 0$$

Camau ar gyfer Datrys Hafaliadau Radical

Tynnu x_{2} o ddwy ochr yr hafaliad.

$$\sqrt{y}+x_{2}-x_{2}=1-x_{2}$$

Mae tynnu x_{2} o’i hun yn gadael 0.

$$\sqrt{y}=1-x_{2}$$

Sgwariwch ddwy ochr yr hafaliad.

$$y=\left(1-x_{2}\right)^{2}$$

Datrys ar gyfer x_2 (complex solution)

$$x_{2}=-\sqrt{y}+1$$

Datrys ar gyfer y (complex solution)

$$y=\left(1-x_{2}\right)^{2}$$

$$x_{2}=1\text{ or }arg(1-x_{2})<\pi$$

Datrys ar gyfer x_2

$$x_{2}=-\sqrt{y}+1$$

$$y\geq 0$$
