Passi Qosra tas-Soluzzjonijiet

Biex iżżid jew tnaqqas l-espressjonijiet, espandihom biex id-denominaturi tagħhom ikunu l-istess. Immultiplika 1 b'\frac{a+2}{a+2}.

$$\frac{\frac{a+2}{a+2}+\frac{1}{a+2}}{\frac{a^{2}-9}{a+2}}$$

Billi \frac{a+2}{a+2} u \frac{1}{a+2} għandhom l-istess denominatur, żidhom billi żżid in-numeraturi tagħhom.

$$\frac{\frac{a+2+1}{a+2}}{\frac{a^{2}-9}{a+2}}$$

Ikkombina termini simili f'a+2+1.

$$\frac{\frac{a+3}{a+2}}{\frac{a^{2}-9}{a+2}}$$

Iddividi \frac{a+3}{a+2} b'\frac{a^{2}-9}{a+2} billi timmultiplika \frac{a+3}{a+2} bir-reċiproku ta' \frac{a^{2}-9}{a+2}.

$$\frac{\left(a+3\right)\left(a+2\right)}{\left(a+2\right)\left(a^{2}-9\right)}$$
