What is the factored form of _________?

enyata [817]

Answer:

Step-by-step explanation:

The expression given is a difference of cubes and factors as

a³ - b³ = (a - b)(a² + ab + b²)

8 $x^{24}$ = (2 $x^{8}$ )³ ⇒ a = 2 $x^{8}$

27 $y^{6}$ = (3y²)³ ⇒ b = 3y²

Hence 2 factors are

(2 $x^{8}$ - 3y²) and

((2 $x^{8}$ )² + (2 $x^{8}$ × 3y²) + (3y²)²)

= (4 $x^{16}$ + 6 $x^{8}$ y² + 9 $y^{4}$ )

Hence the factored form of the expression is C
