Tohaina
Kua tāruatia ki te papatopenga
\frac{9+6b+b^{2}}{9}
Tauwehea te \frac{1}{9}.
\left(b+3\right)^{2}
Whakaarohia te 9+6b+b^{2}. Whakamahia te tikanga tātai pūrua pā, p^{2}+2pq+q^{2}=\left(p+q\right)^{2}, ina p=b, ina q=3.
\frac{\left(b+3\right)^{2}}{9}
Me tuhi anō te kīanga whakatauwehe katoa.
