\frac{10}{x^{2}+15}+\frac{2}{x+3}
Żid 6 u 9 biex tikseb 15.
\frac{10\left(x+3\right)}{\left(x+3\right)\left(x^{2}+15\right)}+\frac{2\left(x^{2}+15\right)}{\left(x+3\right)\left(x^{2}+15\right)}
Biex iżżid jew tnaqqas l-espressjonijiet, espandihom biex id-denominaturi tagħhom ikunu l-istess. L-inqas multiplu komuni ta' x^{2}+15 u x+3 huwa \left(x+3\right)\left(x^{2}+15\right). Immultiplika \frac{10}{x^{2}+15} b'\frac{x+3}{x+3}. Immultiplika \frac{2}{x+3} b'\frac{x^{2}+15}{x^{2}+15}.
\frac{10\left(x+3\right)+2\left(x^{2}+15\right)}{\left(x+3\right)\left(x^{2}+15\right)}
Billi \frac{10\left(x+3\right)}{\left(x+3\right)\left(x^{2}+15\right)} u \frac{2\left(x^{2}+15\right)}{\left(x+3\right)\left(x^{2}+15\right)} għandhom l-istess denominatur, żidhom billi żżid in-numeraturi tagħhom.
\frac{10x+30+2x^{2}+30}{\left(x+3\right)\left(x^{2}+15\right)}
Agħmel il-multiplikazzjonijiet fi 10\left(x+3\right)+2\left(x^{2}+15\right).
\frac{10x+60+2x^{2}}{\left(x+3\right)\left(x^{2}+15\right)}
Ikkombina termini simili f'10x+30+2x^{2}+30.
\frac{10x+60+2x^{2}}{x^{3}+3x^{2}+15x+45}
Espandi \left(x+3\right)\left(x^{2}+15\right).
