Datrys (x^2-3)sqrt{2x+y}=0

$$( { x }^{ 2 } -3) \sqrt{ 2x+y } =0$$

Datrys ar gyfer y

$$\left\{\begin{matrix}\\y=-2x\text{, }&\text{unconditionally}\\y\geq -2x\text{, }&|x|=\sqrt{3}\end{matrix}\right.$$

Camau ar gyfer Datrys Hafaliadau Radical

Rhannu’r ddwy ochr â x^{2}-3.

$$\frac{\left(x^{2}-3\right)\sqrt{y+2x}}{x^{2}-3}=\frac{0}{x^{2}-3}$$

Mae rhannu â x^{2}-3 yn dad-wneud lluosi â x^{2}-3.

$$\sqrt{y+2x}=\frac{0}{x^{2}-3}$$

Rhannwch 0 â x^{2}-3.

$$\sqrt{y+2x}=0$$

Sgwariwch ddwy ochr yr hafaliad.

$$y+2x=0$$

Tynnu 2x o ddwy ochr yr hafaliad.

$$y+2x-2x=-2x$$

Mae tynnu 2x o’i hun yn gadael 0.

$$y=-2x$$

Datrys ar gyfer x (complex solution)

$$x=-\sqrt{3}\approx -1.732050808$$

$$x=\sqrt{3}\approx 1.732050808$$

$$x=-\frac{y}{2}$$

Datrys ar gyfer y (complex solution)

$$\left\{\begin{matrix}\\y=-2x\text{, }&\text{unconditionally}\\y\in \mathrm{C}\text{, }&x=-\sqrt{3}\text{ or }x=\sqrt{3}\end{matrix}\right.$$

Datrys ar gyfer x

$$\left\{\begin{matrix}\\x=-\frac{y}{2}\text{, }&\text{unconditionally}\\x=-\sqrt{3}\text{, }&y\geq 2\sqrt{3}\\x=\sqrt{3}\approx 1.732050808\text{, }&y\geq -2\sqrt{3}\end{matrix}\right.$$
