\frac{\frac{\left(x+4\right)\left(x+4\right)}{\left(x+3\right)\left(x+4\right)}-\frac{\left(x-3\right)\left(x+3\right)}{\left(x+3\right)\left(x+4\right)}}{\frac{14}{x^{2}+7x+12}}
I ychwanegu neu dynnu mynegiannau, rhaid i chi eu ehangu i wneud eu enwaduron yr un fath. Lluosrif lleiaf cyffredin x+3 a x+4 yw \left(x+3\right)\left(x+4\right). Lluoswch \frac{x+4}{x+3} â \frac{x+4}{x+4}. Lluoswch \frac{x-3}{x+4} â \frac{x+3}{x+3}.
\frac{\frac{\left(x+4\right)\left(x+4\right)-\left(x-3\right)\left(x+3\right)}{\left(x+3\right)\left(x+4\right)}}{\frac{14}{x^{2}+7x+12}}
Gan fod gan \frac{\left(x+4\right)\left(x+4\right)}{\left(x+3\right)\left(x+4\right)} a \frac{\left(x-3\right)\left(x+3\right)}{\left(x+3\right)\left(x+4\right)} yr un dynodydd, tynnwch nhw drwy dynnu eu rhifiaduron.
\frac{\frac{x^{2}+4x+4x+16-x^{2}-3x+3x+9}{\left(x+3\right)\left(x+4\right)}}{\frac{14}{x^{2}+7x+12}}
Gwnewch y gwaith lluosi yn \left(x+4\right)\left(x+4\right)-\left(x-3\right)\left(x+3\right).
\frac{\frac{8x+25}{\left(x+3\right)\left(x+4\right)}}{\frac{14}{x^{2}+7x+12}}
Cyfuno termau tebyg yn x^{2}+4x+4x+16-x^{2}-3x+3x+9.
\frac{\left(8x+25\right)\left(x^{2}+7x+12\right)}{\left(x+3\right)\left(x+4\right)\times 14}
Rhannwch \frac{8x+25}{\left(x+3\right)\left(x+4\right)} â \frac{14}{x^{2}+7x+12} drwy luosi \frac{8x+25}{\left(x+3\right)\left(x+4\right)} â chilydd \frac{14}{x^{2}+7x+12}.
\frac{\left(x+3\right)\left(x+4\right)\left(8x+25\right)}{14\left(x+3\right)\left(x+4\right)}
Dylech ffactoreiddio'r mynegiadau sydd heb eu ffactoreiddio eto.
\frac{8x+25}{14}
Canslo \left(x+3\right)\left(x+4\right) yn y rhifiadur a'r enwadur.
