Kua tāruatia ki te papatopenga
a^{2}-2^{2}+4\left(a+1\right)+4
Whakaarohia te \left(a+2\right)\left(a-2\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}-4+4\left(a+1\right)+4
Tātaihia te 2 mā te pū o 2, kia riro ko 4.
a^{2}-4+4a+4+4
Whakamahia te āhuatanga tohatoha hei whakarea te 4 ki te a+1.
a^{2}+4a+4
Tāpirihia te -4 ki te 4, ka 0.
a^{2}-2^{2}+4\left(a+1\right)+4
