$$-fx=6x^{3}+2x^{2}-14x$$

Mae'r hafaliad yn y ffurf safonol.

$$\left(-x\right)f=6x^{3}+2x^{2}-14x$$

Rhannu’r ddwy ochr â -x.

$$\frac{\left(-x\right)f}{-x}=\frac{2x\left(3x^{2}+x-7\right)}{-x}$$

Mae rhannu â -x yn dad-wneud lluosi â -x.

$$f=\frac{2x\left(3x^{2}+x-7\right)}{-x}$$

Rhannwch 2x\left(3x^{2}+x-7\right) â -x.
