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

Gwnewch y gwaith lluosi yn \left(a+1\right)\left(a+1\right)-\left(1-a\right)\left(a-1\right).
\frac{2a^{2}+2}{a\left(a-1\right)\left(a+1\right)}
Cyfuno termau tebyg yn a^{2}+a+a+1-a+1+a^{2}-a.
\frac{2a^{2}+2}{a^{3}-a}

\frac{a^{2}+a+a+1-a+1+a^{2}-a}{a\left(a-1\right)\left(a+1\right)}
Gwnewch y gwaith lluosi yn \left(a+1\right)\left(a+1\right)-\left(1-a\right)\left(a-1\right).
\frac{2a^{2}+2}{a\left(a-1\right)\left(a+1\right)}
Cyfuno termau tebyg yn a^{2}+a+a+1-a+1+a^{2}-a.
