Passi Qosra tas-Soluzzjonijiet

Iffattura a^{2}+2a+1.

$$\frac{a^{2}}{a+1}-\frac{a^{3}}{\left(a+1\right)^{2}}$$

Biex iżżid jew tnaqqas l-espressjonijiet, espandihom biex id-denominaturi tagħhom ikunu l-istess. L-inqas multiplu komuni ta' a+1 u \left(a+1\right)^{2} huwa \left(a+1\right)^{2}. Immultiplika \frac{a^{2}}{a+1} b'\frac{a+1}{a+1}.

$$\frac{a^{2}\left(a+1\right)}{\left(a+1\right)^{2}}-\frac{a^{3}}{\left(a+1\right)^{2}}$$

Billi \frac{a^{2}\left(a+1\right)}{\left(a+1\right)^{2}} u \frac{a^{3}}{\left(a+1\right)^{2}} għandhom l-istess denominatur, naqqashom billi tnaqqas in-numeraturi tagħhom.

$$\frac{a^{2}\left(a+1\right)-a^{3}}{\left(a+1\right)^{2}}$$

Agħmel il-multiplikazzjonijiet fi a^{2}\left(a+1\right)-a^{3}.

$$\frac{a^{3}+a^{2}-a^{3}}{\left(a+1\right)^{2}}$$

Ikkombina termini simili f'a^{3}+a^{2}-a^{3}.

$$\frac{a^{2}}{\left(a+1\right)^{2}}$$

Espandi \left(a+1\right)^{2}.
