Answer 2

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

f) \(\left(x+3\right)\left(x-4\right)=x^2-x-12\)

g) \(\left(x-4\right)\left(x^2+4x+16\right)=x^3-64\)

Answer 3

e: \(\left(x^2-2x+1\right)\left(x-1\right)\)

\(=x^3-3x^2+3x-1\)

f: \(\left(x+3\right)\left(x-4\right)=x^2-x-12\)

g: \(\left(x-4\right)\left(x^2+4x+16\right)=x^3-64\)
