\frac{\left(x-6\right)\left(x-4\right)}{\left(x-4\right)\left(x+4\right)}-\frac{\left(x+2\right)\left(x+4\right)}{\left(x-4\right)\left(x+4\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+4 agus x-4 ná \left(x-4\right)\left(x+4\right). Méadaigh \frac{x-6}{x+4} faoi \frac{x-4}{x-4}. Méadaigh \frac{x+2}{x-4} faoi \frac{x+4}{x+4}.
\frac{\left(x-6\right)\left(x-4\right)-\left(x+2\right)\left(x+4\right)}{\left(x-4\right)\left(x+4\right)}
Tá an t-ainmneoir céanna ag \frac{\left(x-6\right)\left(x-4\right)}{\left(x-4\right)\left(x+4\right)} agus \frac{\left(x+2\right)\left(x+4\right)}{\left(x-4\right)\left(x+4\right)} agus, mar sin, is féidir iad a dhealú trína n-uimhreoirí a dhealú.
\frac{x^{2}-4x-6x+24-x^{2}-4x-2x-8}{\left(x-4\right)\left(x+4\right)}
Déan iolrúcháin in \left(x-6\right)\left(x-4\right)-\left(x+2\right)\left(x+4\right).
\frac{-16x+16}{\left(x-4\right)\left(x+4\right)}
Cumaisc téarmaí comhchosúla in: x^{2}-4x-6x+24-x^{2}-4x-2x-8.
\frac{-16x+16}{x^{2}-16}
Fairsingigh \left(x-4\right)\left(x+4\right)
