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

Chun cothromóidí a shuimiú nó a dhealú, fairsingigh iad chun a n-ainmneoirí a mheaitseáil. Méadaigh 1 faoi \frac{\left(1-x\right)^{2}}{\left(1-x\right)^{2}}.

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

Tá an t-ainmneoir céanna ag \frac{\left(1-x\right)^{2}}{\left(1-x\right)^{2}} agus \frac{kx-k-2x}{\left(1-x\right)^{2}} agus, mar sin, is féidir iad a shuimiú trína n-uimhreoirí a shuimiú.

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

Déan iolrúcháin in \left(1-x\right)^{2}+kx-k-2x.

\frac{1-4x+kx+x^{2}-k}{\left(1-x\right)^{2}}

Cumaisc téarmaí comhchosúla in: 1-2x+x^{2}+kx-k-2x.

\frac{1-4x+kx+x^{2}-k}{x^{2}-2x+1}
