\frac{\frac{x-1}{\left(x-1\right)\left(x+1\right)}-\frac{x+1}{\left(x-1\right)\left(x+1\right)}}{\frac{2}{1-x}}
I ychwanegu neu dynnu mynegiannau, rhaid i chi eu ehangu i wneud eu enwaduron yr un fath. Lluosrif lleiaf cyffredin x+1 a x-1 yw \left(x-1\right)\left(x+1\right). Lluoswch \frac{1}{x+1} â \frac{x-1}{x-1}. Lluoswch \frac{1}{x-1} â \frac{x+1}{x+1}.
\frac{\frac{x-1-\left(x+1\right)}{\left(x-1\right)\left(x+1\right)}}{\frac{2}{1-x}}
Gan fod gan \frac{x-1}{\left(x-1\right)\left(x+1\right)} a \frac{x+1}{\left(x-1\right)\left(x+1\right)} yr un dynodydd, tynnwch nhw drwy dynnu eu rhifiaduron.
\frac{\frac{x-1-x-1}{\left(x-1\right)\left(x+1\right)}}{\frac{2}{1-x}}
Gwnewch y gwaith lluosi yn x-1-\left(x+1\right).
\frac{\frac{-2}{\left(x-1\right)\left(x+1\right)}}{\frac{2}{1-x}}
Cyfuno termau tebyg yn x-1-x-1.
\frac{-2\left(1-x\right)}{\left(x-1\right)\left(x+1\right)\times 2}
Rhannwch \frac{-2}{\left(x-1\right)\left(x+1\right)} â \frac{2}{1-x} drwy luosi \frac{-2}{\left(x-1\right)\left(x+1\right)} â chilydd \frac{2}{1-x}.
\frac{-2\left(-1\right)\left(x-1\right)}{2\left(x-1\right)\left(x+1\right)}
Echdynnwch yr arwydd negatif yn 1-x.
\frac{-\left(-1\right)}{x+1}
Canslo 2\left(x-1\right) yn y rhifiadur a'r enwadur.
\frac{1}{x+1}
Lluosi -1 a -1 i gael 1.
