5x\left(x^{2}+4x+4\right)-2x\left(x-1\right)
Uża teorema binomjali \left(a+b\right)^{2}=a^{2}+2ab+b^{2} biex tespandi \left(x+2\right)^{2}.
5x^{3}+20x^{2}+20x-2x\left(x-1\right)
Uża l-propjetà distributtiva biex timmultiplika 5x b'x^{2}+4x+4.
5x^{3}+20x^{2}+20x-2x^{2}+2x
Uża l-propjetà distributtiva biex timmultiplika -2x b'x-1.
5x^{3}+18x^{2}+20x+2x
Ikkombina 20x^{2} u -2x^{2} biex tikseb 18x^{2}.
5x^{3}+18x^{2}+22x
Ikkombina 20x u 2x biex tikseb 22x.
