Answer:

C

Step-by-step explanation:

The expression given is a difference of cubes and factors as

a³ - b³ = (a - b)(a² + ab + b²)

8[tex]x^{24}[/tex] = (2[tex]x^{8}[/tex])³ ⇒ a = 2[tex]x^{8}[/tex]

27[tex]y^{6}[/tex] = (3y²)³ ⇒ b = 3y²

Hence 2 factors are

(2[tex]x^{8}[/tex] - 3y²) and

((2[tex]x^{8}[/tex])² + (2[tex]x^{8}[/tex] × 3y²) + (3y²)²)

= (4[tex]x^{16}[/tex] + 6[tex]x^{8}[/tex]y² + 9[tex]y^{4}[/tex])

Hence the factored form of the expression is C
