b) \(x^3+6x^2+12x+8=\left(x+2\right)^3\)

c) \(x^3+15x^2+75x+125=\left(x+5\right)^3\)

d) \(x^3-3x^2+3x-1=\left(x-1\right)^3\)

e) \(x^3-6x^2+12x-8=\left(x-2\right)^3\)

f) \(x^3-15x^2+75x-125=\left(x-5\right)^3\)

Answer 2

\(a,x^3+3x^2+3x+1=\left(x+1\right)^3\\ b,x^2+6x+12x+8=\left(x+2\right)^3\\ c,x^3+15x+75x+125=\left(x+5\right)^3\\ d,x^3-3x^2+3x+1=\left(x-1\right)^3\\ e,x^3-6x+12x-8=\left(x-2\right)^3\\ g,x^3-15x^2+75x-125=\left(x-5\right)^3\)
