Datrys left(x-1right)^2=10

$${ \left(x-1 \right) }^{ 2 } =10$$

Datrys ar gyfer x

$$x=\sqrt{10}+1\approx 4.16227766$$

$$x=1-\sqrt{10}\approx -2.16227766$$

Camau drwy Ganfod Isradd

Cymryd isradd dwy ochr yr hafaliad.

$$x-1=\sqrt{10} x-1=-\sqrt{10}$$

Adio 1 at ddwy ochr yr hafaliad.

$$x-1-\left(-1\right)=\sqrt{10}-\left(-1\right) x-1-\left(-1\right)=-\sqrt{10}-\left(-1\right)$$

Mae tynnu -1 o’i hun yn gadael 0.

$$x=\sqrt{10}-\left(-1\right) x=-\sqrt{10}-\left(-1\right)$$

Tynnu -1 o \sqrt{10}.

$$x=\sqrt{10}+1$$

Tynnu -1 o -\sqrt{10}.

$$x=1-\sqrt{10}$$

Mae’r hafaliad wedi’i ddatrys nawr.

$$x=\sqrt{10}+1 x=1-\sqrt{10}$$
