\frac{7\left(t+7\right)}{\left(t-3\right)\left(t+7\right)}-\frac{t\left(t-3\right)}{\left(t-3\right)\left(t+7\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 t-3 agus t+7 ná \left(t-3\right)\left(t+7\right). Méadaigh \frac{7}{t-3} faoi \frac{t+7}{t+7}. Méadaigh \frac{t}{t+7} faoi \frac{t-3}{t-3}.

\frac{7\left(t+7\right)-t\left(t-3\right)}{\left(t-3\right)\left(t+7\right)}

Tá an t-ainmneoir céanna ag \frac{7\left(t+7\right)}{\left(t-3\right)\left(t+7\right)} agus \frac{t\left(t-3\right)}{\left(t-3\right)\left(t+7\right)} agus, mar sin, is féidir iad a dhealú trína n-uimhreoirí a dhealú.

\frac{7t+49-t^{2}+3t}{\left(t-3\right)\left(t+7\right)}

Déan iolrúcháin in 7\left(t+7\right)-t\left(t-3\right).

\frac{10t+49-t^{2}}{\left(t-3\right)\left(t+7\right)}

Cumaisc téarmaí comhchosúla in: 7t+49-t^{2}+3t.

\frac{10t+49-t^{2}}{t^{2}+4t-21}

Fairsingigh \left(t-3\right)\left(t+7\right)
