\frac{3\left(x-1\right)}{\left(x-5\right)\left(x+1\right)}-\frac{2}{x-5}
Ffactora x^{2}-4x-5.
\frac{3\left(x-1\right)}{\left(x-5\right)\left(x+1\right)}-\frac{2\left(x+1\right)}{\left(x-5\right)\left(x+1\right)}
I ychwanegu neu dynnu mynegiannau, rhaid i chi eu ehangu i wneud eu enwaduron yr un fath. Lluosrif lleiaf cyffredin \left(x-5\right)\left(x+1\right) a x-5 yw \left(x-5\right)\left(x+1\right). Lluoswch \frac{2}{x-5} â \frac{x+1}{x+1}.
\frac{3\left(x-1\right)-2\left(x+1\right)}{\left(x-5\right)\left(x+1\right)}
Gan fod gan \frac{3\left(x-1\right)}{\left(x-5\right)\left(x+1\right)} a \frac{2\left(x+1\right)}{\left(x-5\right)\left(x+1\right)} yr un dynodydd, tynnwch nhw drwy dynnu eu rhifiaduron.
\frac{3x-3-2x-2}{\left(x-5\right)\left(x+1\right)}
Gwnewch y gwaith lluosi yn 3\left(x-1\right)-2\left(x+1\right).
\frac{x-5}{\left(x-5\right)\left(x+1\right)}
Cyfuno termau tebyg yn 3x-3-2x-2.
\frac{1}{x+1}
Canslo x-5 yn y rhifiadur a'r enwadur.
