x^{2}\left(49x^{2}-16y^{2}\right)
Whakaarohia te 49x^{4}-16x^{2}y^{2}. Tauwehea te x^{2}.
\left(7x-4y\right)\left(7x+4y\right)
Whakaarohia te 49x^{2}-16y^{2}. Tuhia anō te 49x^{2}-16y^{2} hei \left(7x\right)^{2}-\left(4y\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).
