\frac{6\left(x+5\right)}{\left(x+3\right)\left(x+5\right)}-\frac{2\left(x+3\right)}{\left(x+3\right)\left(x+5\right)}
Biex iżżid jew tnaqqas l-espressjonijiet, espandihom biex id-denominaturi tagħhom ikunu l-istess. L-inqas multiplu komuni ta' x+3 u x+5 huwa \left(x+3\right)\left(x+5\right). Immultiplika \frac{6}{x+3} b'\frac{x+5}{x+5}. Immultiplika \frac{2}{x+5} b'\frac{x+3}{x+3}.
\frac{6\left(x+5\right)-2\left(x+3\right)}{\left(x+3\right)\left(x+5\right)}
Billi \frac{6\left(x+5\right)}{\left(x+3\right)\left(x+5\right)} u \frac{2\left(x+3\right)}{\left(x+3\right)\left(x+5\right)} għandhom l-istess denominatur, naqqashom billi tnaqqas in-numeraturi tagħhom.
\frac{6x+30-2x-6}{\left(x+3\right)\left(x+5\right)}
Agħmel il-multiplikazzjonijiet fi 6\left(x+5\right)-2\left(x+3\right).
