x^{2}-6x+9-\left(x+1\right)^{2}
Uża teorema binomjali \left(a-b\right)^{2}=a^{2}-2ab+b^{2} biex tespandi \left(x-3\right)^{2}.
x^{2}-6x+9-\left(x^{2}+2x+1\right)
Uża teorema binomjali \left(a+b\right)^{2}=a^{2}+2ab+b^{2} biex tespandi \left(x+1\right)^{2}.
x^{2}-6x+9-x^{2}-2x-1
Biex issib l-oppost ta' x^{2}+2x+1, sib l-oppost ta' kull terminu.
-6x+9-2x-1
Ikkombina x^{2} u -x^{2} biex tikseb 0.
-8x+9-1
Ikkombina -6x u -2x biex tikseb -8x.
-8x+8
Naqqas 1 minn 9 biex tikseb 8.
