Kui avaldised pole juba teguriteks lahutatud, tehke seda.

$$\frac{6\left(n-9\right)}{-24\left(n-\left(-\frac{1}{48}\sqrt{1009}+\frac{217}{48}\right)\right)\left(n-\left(\frac{1}{48}\sqrt{1009}+\frac{217}{48}\right)\right)}$$

Taandage 6 nii lugejas kui ka nimetajas.

$$\frac{n-9}{-4\left(n-\left(-\frac{1}{48}\sqrt{1009}+\frac{217}{48}\right)\right)\left(n-\left(\frac{1}{48}\sqrt{1009}+\frac{217}{48}\right)\right)}$$
