Answer 3

\(\left(x-2\right)^3+64\)

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

\(=\left(x-2+4\right)\left[\left(x-2\right)^2-4\left(x-2\right)+4^2\right]\)

\(=\left(x+2\right)\left(x^2-4x+4-4x+8+16\right)\)

\(=\left(x+2\right)\left(x^2-8x+28\right)\)

Answer 4

(x-2)³ + 64

= (x-2)³ + 4³

= (x-2+4).[(x-2)² - (x-2).4 + 4²]

= (x+2).[x² - 4x + 4 - 4x + 8 + 16]

= ( x+2).(x² - 8x + 28)
