x\left(x+2\right)^{2}+2\left(x+2\right)\left(x-2\right)
Immultiplika x+2 u x+2 biex tikseb \left(x+2\right)^{2}.
x\left(x^{2}+4x+4\right)+2\left(x+2\right)\left(x-2\right)
Uża teorema binomjali \left(a+b\right)^{2}=a^{2}+2ab+b^{2} biex tespandi \left(x+2\right)^{2}.
x^{3}+4x^{2}+4x+2\left(x+2\right)\left(x-2\right)
Uża l-propjetà distributtiva biex timmultiplika x b'x^{2}+4x+4.
x^{3}+4x^{2}+4x+\left(2x+4\right)\left(x-2\right)
Uża l-propjetà distributtiva biex timmultiplika 2 b'x+2.
x^{3}+4x^{2}+4x+2x^{2}-4x+4x-8
Applika l-propjetà distributtiva billi timmultiplika kull terminu ta' 2x+4 b'kull terminu ta' x-2.
x^{3}+4x^{2}+4x+2x^{2}-8
Ikkombina -4x u 4x biex tikseb 0.
x^{3}+6x^{2}+4x-8
Ikkombina 4x^{2} u 2x^{2} biex tikseb 6x^{2}.
x\left(x+2\right)^{2}+2\left(x+2\right)\left(x-2\right)
