\frac{\frac{3}{a+1}+\frac{\left(-a+1\right)\left(a+1\right)}{a+1}}{\frac{a^{2}-4a+4}{a+1}}

Chun cothromóidí a shuimiú nó a dhealú, fairsingigh iad chun a n-ainmneoirí a mheaitseáil. Méadaigh -a+1 faoi \frac{a+1}{a+1}.

\frac{\frac{3+\left(-a+1\right)\left(a+1\right)}{a+1}}{\frac{a^{2}-4a+4}{a+1}}

Tá an t-ainmneoir céanna ag \frac{3}{a+1} agus \frac{\left(-a+1\right)\left(a+1\right)}{a+1} agus, mar sin, is féidir iad a shuimiú trína n-uimhreoirí a shuimiú.

\frac{\frac{3-a^{2}-a+a+1}{a+1}}{\frac{a^{2}-4a+4}{a+1}}

Déan iolrúcháin in 3+\left(-a+1\right)\left(a+1\right).

\frac{\frac{4-a^{2}}{a+1}}{\frac{a^{2}-4a+4}{a+1}}

Cumaisc téarmaí comhchosúla in: 3-a^{2}-a+a+1.

\frac{\left(4-a^{2}\right)\left(a+1\right)}{\left(a+1\right)\left(a^{2}-4a+4\right)}

Roinn \frac{4-a^{2}}{a+1} faoi \frac{a^{2}-4a+4}{a+1} trí \frac{4-a^{2}}{a+1} a mhéadú faoi dheilín \frac{a^{2}-4a+4}{a+1}.

\frac{-a^{2}+4}{a^{2}-4a+4}

Cealaigh a+1 mar uimhreoir agus ainmneoir.

\frac{\left(a-2\right)\left(-a-2\right)}{\left(a-2\right)^{2}}

Fachtóirigh na sloinn nach bhfuil fachtóirithe cheana.

\frac{-a-2}{a-2}

Cealaigh a-2 mar uimhreoir agus ainmneoir.
