9x+9-3\left(x+1\right)^{2}
Uża l-propjetà distributtiva biex timmultiplika 9 b'x+1.
9x+9-3\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}.
9x+9-3x^{2}-6x-3
Uża l-propjetà distributtiva biex timmultiplika -3 b'x^{2}+2x+1.
3x+9-3x^{2}-3
Ikkombina 9x u -6x biex tikseb 3x.
3x+6-3x^{2}
Naqqas 3 minn 9 biex tikseb 6.
