\frac{2\left(n-\left(-\frac{1}{4}\sqrt{57}+\frac{5}{4}\right)\right)\left(n-\left(\frac{1}{4}\sqrt{57}+\frac{5}{4}\right)\right)\left(3n^{2}-2n+1\right)}{3n^{2}-2n+1}
I-factor ang mga expression na hindi pa na-factor.
2\left(n-\left(-\frac{1}{4}\sqrt{57}+\frac{5}{4}\right)\right)\left(n-\left(\frac{1}{4}\sqrt{57}+\frac{5}{4}\right)\right)
I-cancel out ang 3n^{2}-2n+1 sa parehong numerator at denominator.
