I ychwanegu neu dynnu mynegiannau, rhaid i chi eu ehangu i wneud eu enwaduron yr un fath. Lluosrif lleiaf cyffredin x\left(x-1\right) a x^{2}\left(x-1\right) yw \left(x-1\right)x^{2}. Lluoswch \frac{2}{x\left(x-1\right)} â \frac{x}{x}.

$$\frac{2x}{\left(x-1\right)x^{2}}-\frac{5}{\left(x-1\right)x^{2}}+\frac{3}{\left(x-1\right)\left(x+1\right)}$$

Gan fod gan \frac{2x}{\left(x-1\right)x^{2}} a \frac{5}{\left(x-1\right)x^{2}} yr un dynodydd, tynnwch nhw drwy dynnu eu rhifiaduron.

$$\frac{\left(2x-5\right)\left(x+1\right)+3x^{2}}{\left(x-1\right)\left(x+1\right)x^{2}}$$

Gwnewch y gwaith lluosi yn \left(2x-5\right)\left(x+1\right)+3x^{2}.

$$\frac{2x^{2}+2x-5x-5+3x^{2}}{\left(x-1\right)\left(x+1\right)x^{2}}$$

Cyfuno termau tebyg yn 2x^{2}+2x-5x-5+3x^{2}.

$$\frac{5x^{2}-3x-5}{\left(x-1\right)\left(x+1\right)x^{2}}$$

Ehangu \left(x-1\right)\left(x+1\right)x^{2}.
