x^{2}+4x+4-\left(x-5\right)\left(x+5\right)
Whakamahia te ture huarua \left(a+b\right)^{2}=a^{2}+2ab+b^{2} hei whakaroha \left(x+2\right)^{2}.
x^{2}+4x+4-\left(x^{2}-25\right)
Whakaarohia te \left(x-5\right)\left(x+5\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}. Pūrua 5.
x^{2}+4x+4-x^{2}+25
Hei kimi i te tauaro o x^{2}-25, kimihia te tauaro o ia taurangi.
4x+4+25
Pahekotia te x^{2} me -x^{2}, ka 0.
4x+29
Tāpirihia te 4 ki te 25, ka 29.
