a^{2}-b^{2}-2a^{2}+b^{2}
Whakaarohia te \left(a-b\right)\left(a+b\right). Ka taea te whakareanga te panoni ki te rerekētanga o ngā pūrua mā te ture: \left(a-b\right)\left(a+b\right)=a^{2}-b^{2}.
-a^{2}-b^{2}+b^{2}
Pahekotia te a^{2} me -2a^{2}, ka -a^{2}.
-a^{2}
Pahekotia te -b^{2} me b^{2}, ka 0.
a^{2}-b^{2}-2a^{2}+b^{2}
Whakaarohia te \left(a-b\right)\left(a+b\right). Ka taea te whakareanga te panoni ki te rerekētanga o ngā pūrua mā te ture: \left(a-b\right)\left(a+b\right)=a^{2}-b^{2}.
-a^{2}-b^{2}+b^{2}
Pahekotia te a^{2} me -2a^{2}, ka -a^{2}.
-a^{2}
Pahekotia te -b^{2} me b^{2}, ka 0.
