\frac{441x^{2}-2500}{225}
Tauwehea te \frac{1}{225}.
\left(21x-50\right)\left(21x+50\right)
Whakaarohia te 441x^{2}-2500. Tuhia anō te 441x^{2}-2500 hei \left(21x\right)^{2}-50^{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(21x-50\right)\left(21x+50\right)}{225}
Me tuhi anō te kīanga whakatauwehe katoa.
