\(a,=-\left(x^3-3x^2+3x-1\right)=-\left(x-1\right)^3=\left(1-x\right)^3\\ b,=\left(2-x\right)^3\\ c,=\left(x-1\right)^3\\ d,=\left(x+1\right)^3\)
\(A=-x^3+3x^2-3x+1=\left(-x+1\right)^3\)
\(B=8-12x+6x^2-x^3=\left(2-x\right)^3\)
\(C=x^3-3x^2+3x-1=\left(x-1\right)^3\)
\(D=x^3+3x^2+3x+1=\left(x+1\right)^3\)
