4\left(q^{4}-4r^{2}\right)
Tauwehea te 4.
\left(q^{2}-2r\right)\left(q^{2}+2r\right)
Whakaarohia te q^{4}-4r^{2}. Tuhia anō te q^{4}-4r^{2} hei \left(q^{2}\right)^{2}-\left(2r\right)^{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).
4\left(q^{2}-2r\right)\left(q^{2}+2r\right)
Me tuhi anō te kīanga whakatauwehe katoa.
