\frac{x+6}{\left(x-2\right)\left(x+2\right)}-\frac{x+5}{x-2}
Fachtóirigh x^{2}-4.
\frac{x+6}{\left(x-2\right)\left(x+2\right)}-\frac{\left(x+5\right)\left(x+2\right)}{\left(x-2\right)\left(x+2\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 \left(x-2\right)\left(x+2\right) agus x-2 ná \left(x-2\right)\left(x+2\right). Méadaigh \frac{x+5}{x-2} faoi \frac{x+2}{x+2}.
\frac{x+6-\left(x+5\right)\left(x+2\right)}{\left(x-2\right)\left(x+2\right)}
Tá an t-ainmneoir céanna ag \frac{x+6}{\left(x-2\right)\left(x+2\right)} agus \frac{\left(x+5\right)\left(x+2\right)}{\left(x-2\right)\left(x+2\right)} agus, mar sin, is féidir iad a dhealú trína n-uimhreoirí a dhealú.
\frac{x+6-x^{2}-2x-5x-10}{\left(x-2\right)\left(x+2\right)}
Déan iolrúcháin in x+6-\left(x+5\right)\left(x+2\right).
\frac{-6x-4-x^{2}}{\left(x-2\right)\left(x+2\right)}
Cumaisc téarmaí comhchosúla in: x+6-x^{2}-2x-5x-10.
\frac{-6x-4-x^{2}}{x^{2}-4}
Fairsingigh \left(x-2\right)\left(x+2\right)
\frac{x+6}{\left(x-2\right)\left(x+2\right)}-\frac{x+5}{x-2}

\frac{x+6-\left(x+5\right)\left(x+2\right)}{\left(x-2\right)\left(x+2\right)}

Déan iolrúcháin in x+6-\left(x+5\right)\left(x+2\right).
\frac{-6x-4-x^{2}}{\left(x-2\right)\left(x+2\right)}
Cumaisc téarmaí comhchosúla in: x+6-x^{2}-2x-5x-10.
\frac{-6x-4-x^{2}}{x^{2}-4}
