Datrys y=(x-3)^2x_{1}

$$y = ( x - 3 ) ^ { 2 } x _ { 1 }$$

Datrys ar gyfer x_1 (complex solution)

$$\left\{\begin{matrix}x_{1}=\frac{y}{\left(x-3\right)^{2}}\text{, }&x\neq 3\\x_{1}\in \mathrm{C}\text{, }&y=0\text{ and }x=3\end{matrix}\right.$$

Camau ar gyfer Datrys Hafaliad Llinol

Defnyddio'r theorem binomaidd \left(a-b\right)^{2}=a^{2}-2ab+b^{2} i ehangu'r \left(x-3\right)^{2}.

$$y=\left(x^{2}-6x+9\right)x_{1}$$

Defnyddio’r briodwedd ddosbarthu i luosi x^{2}-6x+9 â x_{1}.

$$y=x^{2}x_{1}-6xx_{1}+9x_{1}$$

Cyfnewidiwch yr ochrau fel bod yr holl dermau newidiol ar yr ochr chwith.

$$x^{2}x_{1}-6xx_{1}+9x_{1}=y$$

Cyfuno pob term sy'n cynnwys x_{1}.

$$\left(x^{2}-6x+9\right)x_{1}=y$$

Rhannu’r ddwy ochr â x^{2}-6x+9.

$$\frac{\left(x^{2}-6x+9\right)x_{1}}{x^{2}-6x+9}=\frac{y}{x^{2}-6x+9}$$

Mae rhannu â x^{2}-6x+9 yn dad-wneud lluosi â x^{2}-6x+9.

$$x_{1}=\frac{y}{x^{2}-6x+9}$$

Rhannwch y â x^{2}-6x+9.

$$x_{1}=\frac{y}{\left(x-3\right)^{2}}$$
