5 raruraru e ōrite ana ki:
\frac { 4 } { 9 } b ^ { 2 } + \frac { 9 } { 4 } a ^ { 2 } - 2 a b

Kua tāruatia ki te papatopenga
\frac{16b^{2}+81a^{2}-72ab}{36}
Tauwehea te \frac{1}{36}.
\left(-9a+4b\right)^{2}
Whakaarohia te 16b^{2}+81a^{2}-72ab. Whakamahia te tikanga tātai pūrua pā, p^{2}+2pq+q^{2}=\left(p+q\right)^{2}, ina p=-9a, ina q=4b.
\frac{\left(-9a+4b\right)^{2}}{36}
Me tuhi anō te kīanga whakatauwehe katoa.
