Passi Qosra tas-Soluzzjonijiet

Biex iżżid jew tnaqqas l-espressjonijiet, espandihom biex id-denominaturi tagħhom ikunu l-istess. Immultiplika 1 b'\frac{\left(1-x\right)^{2}}{\left(1-x\right)^{2}}.

$$\frac{\left(1-x\right)^{2}}{\left(1-x\right)^{2}}+\frac{kx-k-2x}{\left(1-x\right)^{2}}$$

Billi \frac{\left(1-x\right)^{2}}{\left(1-x\right)^{2}} u \frac{kx-k-2x}{\left(1-x\right)^{2}} għandhom l-istess denominatur, żidhom billi żżid in-numeraturi tagħhom.
