Datrys x*(y+2)*(y-3)=-12

$$x \times (y+2) \times (y-3)=-12$$

Datrys ar gyfer x

$$x=-\frac{12}{\left(y-3\right)\left(y+2\right)}$$

$$y\neq -2\text{ and }y\neq 3$$

Camau ar gyfer Datrys Hafaliad Llinol

Defnyddio’r briodwedd ddosbarthu i luosi x â y+2.

$$\left(xy+2x\right)\left(y-3\right)=-12$$

Defnyddio’r briodwedd ddosbarthu i luosi xy+2x â y-3 a chyfuno termau tebyg.

$$xy^{2}-xy-6x=-12$$

Cyfuno pob term sy'n cynnwys x.

$$\left(y^{2}-y-6\right)x=-12$$

Rhannu’r ddwy ochr â y^{2}-y-6.

$$\frac{\left(y^{2}-y-6\right)x}{y^{2}-y-6}=-\frac{12}{y^{2}-y-6}$$

Mae rhannu â y^{2}-y-6 yn dad-wneud lluosi â y^{2}-y-6.

$$x=-\frac{12}{y^{2}-y-6}$$

Rhannwch -12 â y^{2}-y-6.

$$x=-\frac{12}{\left(y-3\right)\left(y+2\right)}$$

Datrys ar gyfer y (complex solution)

$$y=\frac{\sqrt{x\left(25x-48\right)}+x}{2x}$$

$$y=\frac{-\sqrt{x\left(25x-48\right)}+x}{2x}\text{, }x\neq 0$$

Datrys ar gyfer y

$$y=\frac{\sqrt{x\left(25x-48\right)}+x}{2x}$$

$$y=\frac{-\sqrt{x\left(25x-48\right)}+x}{2x}\text{, }x<0\text{ or }x\geq \frac{48}{25}$$
