\frac{10\left(a-\left(-\frac{1}{20}\sqrt{305}-\frac{3}{4}\right)\right)\left(a-\left(\frac{1}{20}\sqrt{305}-\frac{3}{4}\right)\right)}{5a}
I-factor ang mga expression na hindi pa na-factor.
\frac{2\left(a-\left(-\frac{1}{20}\sqrt{305}-\frac{3}{4}\right)\right)\left(a-\left(\frac{1}{20}\sqrt{305}-\frac{3}{4}\right)\right)}{a}
I-cancel out ang 5 sa parehong numerator at denominator.
