\frac{4x^{4}+4x^{2}+1}{4}
Tauwehea te \frac{1}{4}.
\left(2x^{2}+1\right)^{2}
Whakaarohia te 4x^{4}+4x^{2}+1. Whakamahia te tikanga tātai pūrua pā, a^{2}+2ab+b^{2}=\left(a+b\right)^{2}, ina a=2x^{2}, ina b=1.
\frac{\left(2x^{2}+1\right)^{2}}{4}
Me tuhi anō te kīanga whakatauwehe katoa. Kāore te pūrau 2x^{2}+1 i whakatauwehea i te mea kāhore ōna pūtake whakahau.
