\frac{x-1}{\left(x+1\right)\left(x+3\right)}+\frac{2}{\left(x+2\right)\left(x+3\right)}
Ffactora x^{2}+4x+3. Ffactora x^{2}+5x+6.
\frac{\left(x-1\right)\left(x+2\right)}{\left(x+1\right)\left(x+2\right)\left(x+3\right)}+\frac{2\left(x+1\right)}{\left(x+1\right)\left(x+2\right)\left(x+3\right)}
I ychwanegu neu dynnu mynegiannau, rhaid i chi eu ehangu i wneud eu enwaduron yr un fath. Lluosrif lleiaf cyffredin \left(x+1\right)\left(x+3\right) a \left(x+2\right)\left(x+3\right) yw \left(x+1\right)\left(x+2\right)\left(x+3\right). Lluoswch \frac{x-1}{\left(x+1\right)\left(x+3\right)} â \frac{x+2}{x+2}. Lluoswch \frac{2}{\left(x+2\right)\left(x+3\right)} â \frac{x+1}{x+1}.
\frac{\left(x-1\right)\left(x+2\right)+2\left(x+1\right)}{\left(x+1\right)\left(x+2\right)\left(x+3\right)}
Gan fod gan \frac{\left(x-1\right)\left(x+2\right)}{\left(x+1\right)\left(x+2\right)\left(x+3\right)} a \frac{2\left(x+1\right)}{\left(x+1\right)\left(x+2\right)\left(x+3\right)} yr un dynodydd, adiwch nhw drwy adio eu rhifiaduron.
\frac{x^{2}+2x-x-2+2x+2}{\left(x+1\right)\left(x+2\right)\left(x+3\right)}
Gwnewch y gwaith lluosi yn \left(x-1\right)\left(x+2\right)+2\left(x+1\right).
\frac{x^{2}+3x}{\left(x+1\right)\left(x+2\right)\left(x+3\right)}
Cyfuno termau tebyg yn x^{2}+2x-x-2+2x+2.
\frac{x\left(x+3\right)}{\left(x+1\right)\left(x+2\right)\left(x+3\right)}
Dylech ffactoreiddio'r mynegiadau sydd heb eu ffactoreiddio eisoes yn \frac{x^{2}+3x}{\left(x+1\right)\left(x+2\right)\left(x+3\right)}.
\frac{x}{\left(x+1\right)\left(x+2\right)}
Canslo x+3 yn y rhifiadur a'r enwadur.
\frac{x}{x^{2}+3x+2}
Ehangu \left(x+1\right)\left(x+2\right).
\frac{x-1}{\left(x+1\right)\left(x+3\right)}+\frac{2}{\left(x+2\right)\left(x+3\right)}

Lluoswch \frac{x-1}{\left(x+1\right)\left(x+3\right)} â \frac{x+2}{x+2}. Lluoswch \frac{2}{\left(x+2\right)\left(x+3\right)} â \frac{x+1}{x+1}.
\frac{\left(x-1\right)\left(x+2\right)+2\left(x+1\right)}{\left(x+1\right)\left(x+2\right)\left(x+3\right)}
Gan fod gan \frac{\left(x-1\right)\left(x+2\right)}{\left(x+1\right)\left(x+2\right)\left(x+3\right)} a \frac{2\left(x+1\right)}{\left(x+1\right)\left(x+2\right)\left(x+3\right)} yr un dynodydd, adiwch nhw drwy adio eu rhifiaduron.
