Datrys (x-3)^2-10=0

$$( x - 3 ) ^ { 2 } - 10 = 0$$

Datrys ar gyfer x

$$x=\sqrt{10}+3\approx 6.16227766$$

$$x=3-\sqrt{10}\approx -0.16227766$$

Adio 10 at ddwy ochr yr hafaliad.

$$\left(x-3\right)^{2}-10+10=10$$

Mae tynnu 10 o’i hun yn gadael 0.

$$\left(x-3\right)^{2}=10$$

Cymryd isradd dwy ochr yr hafaliad.

$$x-3=\sqrt{10} x-3=-\sqrt{10}$$

Adio 3 at ddwy ochr yr hafaliad.

$$x-3-\left(-3\right)=\sqrt{10}-\left(-3\right) x-3-\left(-3\right)=-\sqrt{10}-\left(-3\right)$$

Mae tynnu -3 o’i hun yn gadael 0.

$$x=\sqrt{10}-\left(-3\right) x=-\sqrt{10}-\left(-3\right)$$

Tynnu -3 o \sqrt{10}.

$$x=\sqrt{10}+3$$

Tynnu -3 o -\sqrt{10}.

$$x=3-\sqrt{10}$$

Mae’r hafaliad wedi’i ddatrys nawr.

$$x=\sqrt{10}+3 x=3-\sqrt{10}$$
