\frac{4x^{2}-1}{36}
Tauwehea te \frac{1}{36}.
\left(2x-1\right)\left(2x+1\right)
Whakaarohia te 4x^{2}-1. Tuhia anō te 4x^{2}-1 hei \left(2x\right)^{2}-1^{2}. Ka taea te rerekētanga o ngā pūrua te whakatauwehe mā te ture: a^{2}-b^{2}=\left(a-b\right)\left(a+b\right).
\frac{\left(2x-1\right)\left(2x+1\right)}{36}
Me tuhi anō te kīanga whakatauwehe katoa.
