8y^{3}-12y^{2}+6y-1-3\left(2y-1\right)^{2}
Uża teorema binomjali \left(a-b\right)^{3}=a^{3}-3a^{2}b+3ab^{2}-b^{3} biex tespandi \left(2y-1\right)^{3}.
8y^{3}-12y^{2}+6y-1-3\left(4y^{2}-4y+1\right)
Uża teorema binomjali \left(a-b\right)^{2}=a^{2}-2ab+b^{2} biex tespandi \left(2y-1\right)^{2}.
8y^{3}-12y^{2}+6y-1-12y^{2}+12y-3
Uża l-propjetà distributtiva biex timmultiplika -3 b'4y^{2}-4y+1.
8y^{3}-24y^{2}+6y-1+12y-3
Ikkombina -12y^{2} u -12y^{2} biex tikseb -24y^{2}.
8y^{3}-24y^{2}+18y-1-3
Ikkombina 6y u 12y biex tikseb 18y.
8y^{3}-24y^{2}+18y-4
Naqqas 3 minn -1 biex tikseb -4.
8y^{3}-12y^{2}+6y-1-3\left(2y-1\right)^{2}
