\left(x+5\right)^{2}-\left(x-5\right)^{2}
Immultiplika x+5 u x+5 biex tikseb \left(x+5\right)^{2}.
x^{2}+10x+25-\left(x-5\right)^{2}
Uża teorema binomjali \left(a+b\right)^{2}=a^{2}+2ab+b^{2} biex tespandi \left(x+5\right)^{2}.
x^{2}+10x+25-\left(x^{2}-10x+25\right)
Uża teorema binomjali \left(a-b\right)^{2}=a^{2}-2ab+b^{2} biex tespandi \left(x-5\right)^{2}.
x^{2}+10x+25-x^{2}+10x-25
Biex issib l-oppost ta' x^{2}-10x+25, sib l-oppost ta' kull terminu.
10x+25+10x-25
Ikkombina x^{2} u -x^{2} biex tikseb 0.
20x+25-25
Ikkombina 10x u 10x biex tikseb 20x.
20x
Naqqas 25 minn 25 biex tikseb 0.
