\left(a^{2}-4a+4\right)\left(a+2\right)^{2}
Whakamahia te ture huarua \left(p-q\right)^{2}=p^{2}-2pq+q^{2} hei whakaroha \left(a-2\right)^{2}.
\left(a^{2}-4a+4\right)\left(a^{2}+4a+4\right)
Whakamahia te ture huarua \left(p+q\right)^{2}=p^{2}+2pq+q^{2} hei whakaroha \left(a+2\right)^{2}.
a^{4}-8a^{2}+16
Whakamahia te āhuatanga tuaritanga hei whakarea te a^{2}-4a+4 ki te a^{2}+4a+4 ka whakakotahi i ngā kupu rite.
\left(a^{2}-4a+4\right)\left(a+2\right)^{2}
Whakamahia te ture huarua \left(p-q\right)^{2}=p^{2}-2pq+q^{2} hei whakaroha \left(a-2\right)^{2}.
\left(a^{2}-4a+4\right)\left(a^{2}+4a+4\right)
