Answer:
[tex]x^{6}[/tex] - 8
Step-by-step explanation:
A difference of cubes has the form
a³ - b³
Note that [tex]x^{6}[/tex] is a perfect cube, that is [tex](x^2)^{3}[/tex], but
[tex]x^{8}[/tex] is not
8 is a perfect cube, that is 2³ , but 6 is not
Thus
[tex]x^{6}[/tex] - 8 ← is a difference of cubes
= [tex](x^2)^{3}[/tex] - 2³
