\frac{24\left(3x+1\right)}{\left(x-3\right)\left(3x+1\right)}+\frac{15\left(x-3\right)}{\left(x-3\right)\left(3x+1\right)}
I ychwanegu neu dynnu mynegiannau, rhaid i chi eu ehangu i wneud eu enwaduron yr un fath. Lluosrif lleiaf cyffredin x-3 a 3x+1 yw \left(x-3\right)\left(3x+1\right). Lluoswch \frac{24}{x-3} â \frac{3x+1}{3x+1}. Lluoswch \frac{15}{3x+1} â \frac{x-3}{x-3}.
\frac{24\left(3x+1\right)+15\left(x-3\right)}{\left(x-3\right)\left(3x+1\right)}
Gan fod gan \frac{24\left(3x+1\right)}{\left(x-3\right)\left(3x+1\right)} a \frac{15\left(x-3\right)}{\left(x-3\right)\left(3x+1\right)} yr un dynodydd, adiwch nhw drwy adio eu rhifiaduron.
\frac{72x+24+15x-45}{\left(x-3\right)\left(3x+1\right)}
Gwnewch y gwaith lluosi yn 24\left(3x+1\right)+15\left(x-3\right).
\frac{87x-21}{\left(x-3\right)\left(3x+1\right)}
Cyfuno termau tebyg yn 72x+24+15x-45.
\frac{87x-21}{3x^{2}-8x-3}
Ehangu \left(x-3\right)\left(3x+1\right).
