16\left(x^{2}-2x+1\right)-\left(x+2\right)^{2}
Uża teorema binomjali \left(a-b\right)^{2}=a^{2}-2ab+b^{2} biex tespandi \left(x-1\right)^{2}.
16x^{2}-32x+16-\left(x+2\right)^{2}
Uża l-propjetà distributtiva biex timmultiplika 16 b'x^{2}-2x+1.
16x^{2}-32x+16-\left(x^{2}+4x+4\right)
Uża teorema binomjali \left(a+b\right)^{2}=a^{2}+2ab+b^{2} biex tespandi \left(x+2\right)^{2}.
16x^{2}-32x+16-x^{2}-4x-4
Biex issib l-oppost ta' x^{2}+4x+4, sib l-oppost ta' kull terminu.
15x^{2}-32x+16-4x-4
Ikkombina 16x^{2} u -x^{2} biex tikseb 15x^{2}.
15x^{2}-36x+16-4
Ikkombina -32x u -4x biex tikseb -36x.
15x^{2}-36x+12
Naqqas 4 minn 16 biex tikseb 12.
16\left(x^{2}-2x+1\right)-\left(x+2\right)^{2}
