Answer 1

Answer:

$= 27 {x}^{3} + 8 {y}^{3} \\ \\ = {(3x)}^{3} + {(2y)}^{3} \\ \\ = (3x + 2y)( {(3x)}^{2} - 3x.2x + {(2y)}^{2} ) \\ \\ = (3x + 2y)(9 {x}^{2} - 6xy + 8 {y}^{2} )$

Answer 2

Answer:

(3x + 2y)(9x² - 6xy + 4y²)

Step-by-step explanation:

a³ + b³ = (a + b)(a² - ab + b²)

a³ - b³ = (a - b)(a² + ab + b²)

~~~~~~~~

27x³ + 8y³ = (3x)³ + (2y)³

(3x + 2y)[(3x)² - 3x × 2y + (2y)²]

(3x + 2y)(9x² - 6xy + 4y²)
