\frac{2}{\left(x+2\right)\left(x-3\right)^{2}}-\frac{3x}{5\left(x^{2}-3\right)}
Ffactora x^{3}-4x^{2}-3x+18. Ffactora 5x^{2}-15.
\frac{2\times 5\left(x^{2}-3\right)}{5\left(x+2\right)\left(x-3\right)^{2}\left(x^{2}-3\right)}-\frac{3x\left(x+2\right)\left(x-3\right)^{2}}{5\left(x+2\right)\left(x-3\right)^{2}\left(x^{2}-3\right)}
I ychwanegu neu dynnu mynegiannau, rhaid i chi eu ehangu i wneud eu enwaduron yr un fath. Lluosrif lleiaf cyffredin \left(x+2\right)\left(x-3\right)^{2} a 5\left(x^{2}-3\right) yw 5\left(x+2\right)\left(x-3\right)^{2}\left(x^{2}-3\right). Lluoswch \frac{2}{\left(x+2\right)\left(x-3\right)^{2}} â \frac{5\left(x^{2}-3\right)}{5\left(x^{2}-3\right)}. Lluoswch \frac{3x}{5\left(x^{2}-3\right)} â \frac{\left(x+2\right)\left(x-3\right)^{2}}{\left(x+2\right)\left(x-3\right)^{2}}.
