\frac{x\left(x-1\right)}{\left(x-2\right)\left(x-1\right)}-\frac{x\left(x-2\right)}{\left(x-2\right)\left(x-1\right)}
Chun cothromóidí a shuimiú nó a dhealú, fairsingigh iad chun a n-ainmneoirí a mheaitseáil. Is é an t-iolrach is lú coitianta de x-2 agus x-1 ná \left(x-2\right)\left(x-1\right). Méadaigh \frac{x}{x-2} faoi \frac{x-1}{x-1}. Méadaigh \frac{x}{x-1} faoi \frac{x-2}{x-2}.
\frac{x\left(x-1\right)-x\left(x-2\right)}{\left(x-2\right)\left(x-1\right)}
Tá an t-ainmneoir céanna ag \frac{x\left(x-1\right)}{\left(x-2\right)\left(x-1\right)} agus \frac{x\left(x-2\right)}{\left(x-2\right)\left(x-1\right)} agus, mar sin, is féidir iad a dhealú trína n-uimhreoirí a dhealú.
\frac{x^{2}-x-x^{2}+2x}{\left(x-2\right)\left(x-1\right)}
Déan iolrúcháin in x\left(x-1\right)-x\left(x-2\right).
\frac{x}{\left(x-2\right)\left(x-1\right)}
Cumaisc téarmaí comhchosúla in: x^{2}-x-x^{2}+2x.
\frac{x}{x^{2}-3x+2}
Fairsingigh \left(x-2\right)\left(x-1\right)
