Datrys 1/x-1/x+1/frac{1{x}+1/x+1}

$$\frac { \frac { 1 } { x } - \frac { 1 } { x + 1 } } { \frac { 1 } { x } + \frac { 1 } { x + 1 } }$$

Enrhifo

$$\frac{1}{2x+1}$$

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

$$\frac{\frac{x+1}{x\left(x+1\right)}-\frac{x}{x\left(x+1\right)}}{\frac{1}{x}+\frac{1}{x+1}}$$

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

$$\frac{\frac{x+1-x}{x\left(x+1\right)}}{\frac{1}{x}+\frac{1}{x+1}}$$

Cyfuno termau tebyg yn x+1-x.

$$\frac{\frac{1}{x\left(x+1\right)}}{\frac{x+1}{x\left(x+1\right)}+\frac{x}{x\left(x+1\right)}}$$

Gan fod gan \frac{x+1}{x\left(x+1\right)} a \frac{x}{x\left(x+1\right)} yr un dynodydd, adiwch nhw drwy adio eu rhifiaduron.

$$\frac{\frac{1}{x\left(x+1\right)}}{\frac{x+1+x}{x\left(x+1\right)}}$$

Cyfuno termau tebyg yn x+1+x.

$$\frac{\frac{1}{x\left(x+1\right)}}{\frac{2x+1}{x\left(x+1\right)}}$$

Rhannwch \frac{1}{x\left(x+1\right)} â \frac{2x+1}{x\left(x+1\right)} drwy luosi \frac{1}{x\left(x+1\right)} â chilydd \frac{2x+1}{x\left(x+1\right)}.

$$\frac{x\left(x+1\right)}{x\left(x+1\right)\left(2x+1\right)}$$

Canslo x\left(x+1\right) yn y rhifiadur a'r enwadur.
