\frac{3}{2\left(x+5\right)}+\frac{5}{x+2}
Fachtóirigh 2x+10.
\frac{3\left(x+2\right)}{2\left(x+2\right)\left(x+5\right)}+\frac{5\times 2\left(x+5\right)}{2\left(x+2\right)\left(x+5\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 2\left(x+5\right) agus x+2 ná 2\left(x+2\right)\left(x+5\right). Méadaigh \frac{3}{2\left(x+5\right)} faoi \frac{x+2}{x+2}. Méadaigh \frac{5}{x+2} faoi \frac{2\left(x+5\right)}{2\left(x+5\right)}.
\frac{3\left(x+2\right)+5\times 2\left(x+5\right)}{2\left(x+2\right)\left(x+5\right)}
Tá an t-ainmneoir céanna ag \frac{3\left(x+2\right)}{2\left(x+2\right)\left(x+5\right)} agus \frac{5\times 2\left(x+5\right)}{2\left(x+2\right)\left(x+5\right)} agus, mar sin, is féidir iad a shuimiú trína n-uimhreoirí a shuimiú.
