Tauwehea te 3.
\left(5n^{2}-2\right)^{2}
Whakaarohia te 25n^{4}-20n^{2}+4. Whakamahia te tikanga tātai pūrua pā, a^{2}-2ab+b^{2}=\left(a-b\right)^{2}, ina a=5n^{2}, ina b=2.
3\left(5n^{2}-2\right)^{2}
Me tuhi anō te kīanga whakatauwehe katoa. Kāore te pūrau 5n^{2}-2 i whakatauwehea i te mea kāhore ōna pūtake whakahau.
