\frac{1}{\left(x+1\right)^{2}}-\frac{3x}{x+1}
Iffattura x^{2}+2x+1.
\frac{1}{\left(x+1\right)^{2}}-\frac{3x\left(x+1\right)}{\left(x+1\right)^{2}}
Biex iżżid jew tnaqqas l-espressjonijiet, espandihom biex id-denominaturi tagħhom ikunu l-istess. L-inqas multiplu komuni ta' \left(x+1\right)^{2} u x+1 huwa \left(x+1\right)^{2}. Immultiplika \frac{3x}{x+1} b'\frac{x+1}{x+1}.
\frac{1-3x\left(x+1\right)}{\left(x+1\right)^{2}}
Billi \frac{1}{\left(x+1\right)^{2}} u \frac{3x\left(x+1\right)}{\left(x+1\right)^{2}} għandhom l-istess denominatur, naqqashom billi tnaqqas in-numeraturi tagħhom.
\frac{1-3x^{2}-3x}{\left(x+1\right)^{2}}
Agħmel il-multiplikazzjonijiet fi 1-3x\left(x+1\right).
\frac{1-3x^{2}-3x}{x^{2}+2x+1}
Espandi \left(x+1\right)^{2}.
