Céimeanna gearra réitigh

Roinn \frac{2m-8a^{2}m}{1+2a} faoi \frac{4am^{2}-2m^{2}}{2am^{2}-m} trí \frac{2m-8a^{2}m}{1+2a} a mhéadú faoi dheilín \frac{4am^{2}-2m^{2}}{2am^{2}-m}.

$$\frac{\left(2m-8a^{2}m\right)\left(2am^{2}-m\right)}{\left(1+2a\right)\left(4am^{2}-2m^{2}\right)}$$

Fachtóirigh na sloinn nach bhfuil fachtóirithe cheana.

$$\frac{2\left(-2a-1\right)\left(2a-1\right)m^{2}\left(2am-1\right)}{2\left(2a-1\right)\left(2a+1\right)m^{2}}$$

Bain an comhartha diúltach in: -1-2a.

$$\frac{-2\left(2a-1\right)\left(2a+1\right)m^{2}\left(2am-1\right)}{2\left(2a-1\right)\left(2a+1\right)m^{2}}$$

Cealaigh 2\left(2a-1\right)\left(2a+1\right)m^{2} mar uimhreoir agus ainmneoir.
