\left(x+5\right)^{2}-\left(x-5\right)^{2}
Whakareatia te x+5 ki te x+5, ka \left(x+5\right)^{2}.
x^{2}+10x+25-\left(x-5\right)^{2}
Whakamahia te ture huarua \left(a+b\right)^{2}=a^{2}+2ab+b^{2} hei whakaroha \left(x+5\right)^{2}.
x^{2}+10x+25-\left(x^{2}-10x+25\right)
Whakamahia te ture huarua \left(a-b\right)^{2}=a^{2}-2ab+b^{2} hei whakaroha \left(x-5\right)^{2}.
x^{2}+10x+25-x^{2}+10x-25
Hei kimi i te tauaro o x^{2}-10x+25, kimihia te tauaro o ia taurangi.
