\left(x+1\right)\left(\frac{2\left(x+1\right)}{x\left(x+1\right)}+\frac{x}{x\left(x+1\right)}\right)
Biex iżżid jew tnaqqas l-espressjonijiet, espandihom biex id-denominaturi tagħhom ikunu l-istess. L-inqas multiplu komuni ta' x u x+1 huwa x\left(x+1\right). Immultiplika \frac{2}{x} b'\frac{x+1}{x+1}. Immultiplika \frac{1}{x+1} b'\frac{x}{x}.
\left(x+1\right)\times \frac{2\left(x+1\right)+x}{x\left(x+1\right)}
Billi \frac{2\left(x+1\right)}{x\left(x+1\right)} u \frac{x}{x\left(x+1\right)} għandhom l-istess denominatur, żidhom billi żżid in-numeraturi tagħhom.
\left(x+1\right)\times \frac{2x+2+x}{x\left(x+1\right)}
Agħmel il-multiplikazzjonijiet fi 2\left(x+1\right)+x.
\left(x+1\right)\times \frac{3x+2}{x\left(x+1\right)}
Ikkombina termini simili f'2x+2+x.
\frac{\left(x+1\right)\left(3x+2\right)}{x\left(x+1\right)}
Esprimi \left(x+1\right)\times \frac{3x+2}{x\left(x+1\right)} bħala frazzjoni waħda.
\frac{3x+2}{x}
Annulla x+1 fin-numeratur u d-denominatur.
\left(x+1\right)\left(\frac{2\left(x+1\right)}{x\left(x+1\right)}+\frac{x}{x\left(x+1\right)}\right)
Biex iżżid jew tnaqqas l-espressjonijiet, espandihom biex id-denominaturi tagħhom ikunu l-istess. L-inqas multiplu komuni ta' x u x+1 huwa x\left(x+1\right). Immultiplika \frac{2}{x} b'\frac{x+1}{x+1}. Immultiplika \frac{1}{x+1} b'\frac{x}{x}.
\left(x+1\right)\times \frac{2\left(x+1\right)+x}{x\left(x+1\right)}
Billi \frac{2\left(x+1\right)}{x\left(x+1\right)} u \frac{x}{x\left(x+1\right)} għandhom l-istess denominatur, żidhom billi żżid in-numeraturi tagħhom.
\left(x+1\right)\times \frac{2x+2+x}{x\left(x+1\right)}
