\left(-x\right)^{2}+6\left(-x\right)+9-2\left(2x-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}+6\left(-x\right)+9-2\left(2x-1\right)^{2}
Ikkalkula -x bil-power ta' 2 u tikseb x^{2}.
x^{2}+6\left(-x\right)+9-2\left(4x^{2}-4x+1\right)
Uża teorema binomjali \left(a-b\right)^{2}=a^{2}-2ab+b^{2} biex tespandi \left(2x-1\right)^{2}.
x^{2}+6\left(-x\right)+9-8x^{2}+8x-2
Uża l-propjetà distributtiva biex timmultiplika -2 b'4x^{2}-4x+1.
-7x^{2}+6\left(-x\right)+9+8x-2
Ikkombina x^{2} u -8x^{2} biex tikseb -7x^{2}.
-7x^{2}+6\left(-x\right)+7+8x
Naqqas 2 minn 9 biex tikseb 7.
-7x^{2}-6x+7+8x
Immultiplika 6 u -1 biex tikseb -6.
-7x^{2}+2x+7
Ikkombina -6x u 8x biex tikseb 2x.
