\left(x-1\right)^{2}-\left(x-2\right)\times 2
Immultiplika x-1 u x-1 biex tikseb \left(x-1\right)^{2}.
x^{2}-2x+1-\left(x-2\right)\times 2
Uża teorema binomjali \left(a-b\right)^{2}=a^{2}-2ab+b^{2} biex tespandi \left(x-1\right)^{2}.
x^{2}-2x+1-\left(2x-4\right)
Uża l-propjetà distributtiva biex timmultiplika x-2 b'2.
x^{2}-2x+1-2x-\left(-4\right)
Biex issib l-oppost ta' 2x-4, sib l-oppost ta' kull terminu.
x^{2}-2x+1-2x+4
L-oppost ta' -4 huwa 4.
x^{2}-4x+1+4
Ikkombina -2x u -2x biex tikseb -4x.
x^{2}-4x+5
Żid 1 u 4 biex tikseb 5.
