Datrys 1/3x*x*x-2x^2+3x

$$\frac{ 1 }{ 3 } x \times x \times x-2 { x }^{ 2 } +3x$$

Enrhifo

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

Camau Ateb

Lluosi x a x i gael x^{2}.

$$\frac{1}{3}x^{2}x-2x^{2}+3x$$

Er mwyn lluosi pwerau sy’n rhannu’r un sail, adiwch eu esbonyddion. Adiwch 2 a 1 i gael 3.

$$\frac{1}{3}x^{3}-2x^{2}+3x$$

Ffactor

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

Camau Ateb

Ffactora allan \frac{1}{3}.

$$\frac{xxx-6x^{2}+9x}{3}$$

Ystyriwch x^{3}-6x^{2}+9x. Ffactora allan x.

$$x\left(x^{2}-6x+9\right)$$

Ystyriwch x^{2}-6x+9. Defnyddiwch y fformiwla sgwâr perffaith, a^{2}-2ab+b^{2}=\left(a-b\right)^{2}, lle a=x a b=3.

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

Ailysgrifennwch y mynegiad cyfan wedi'i ffactorio.

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