\frac{\frac{3}{a-1}+\frac{a-3}{\left(a-1\right)\left(a+1\right)}}{\frac{a}{a+1}}

Ffactora a^{2}-1.

\frac{\frac{3\left(a+1\right)}{\left(a-1\right)\left(a+1\right)}+\frac{a-3}{\left(a-1\right)\left(a+1\right)}}{\frac{a}{a+1}}

I ychwanegu neu dynnu mynegiannau, rhaid i chi eu ehangu i wneud eu enwaduron yr un fath. Lluosrif lleiaf cyffredin a-1 a \left(a-1\right)\left(a+1\right) yw \left(a-1\right)\left(a+1\right). Lluoswch \frac{3}{a-1} â \frac{a+1}{a+1}.

\frac{\frac{3\left(a+1\right)+a-3}{\left(a-1\right)\left(a+1\right)}}{\frac{a}{a+1}}

Gan fod gan \frac{3\left(a+1\right)}{\left(a-1\right)\left(a+1\right)} a \frac{a-3}{\left(a-1\right)\left(a+1\right)} yr un dynodydd, adiwch nhw drwy adio eu rhifiaduron.

\frac{\frac{3a+3+a-3}{\left(a-1\right)\left(a+1\right)}}{\frac{a}{a+1}}

Gwnewch y gwaith lluosi yn 3\left(a+1\right)+a-3.

\frac{\frac{4a}{\left(a-1\right)\left(a+1\right)}}{\frac{a}{a+1}}

Cyfuno termau tebyg yn 3a+3+a-3.

\frac{4a\left(a+1\right)}{\left(a-1\right)\left(a+1\right)a}

Rhannwch \frac{4a}{\left(a-1\right)\left(a+1\right)} â \frac{a}{a+1} drwy luosi \frac{4a}{\left(a-1\right)\left(a+1\right)} â chilydd \frac{a}{a+1}.

\frac{4}{a-1}

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