Answer 2

Given:

$54 {x}^{3} + 128y ^{3}$

To find:

the solution

STEP BY STEP EXPLANATION:

$54 {x}^{3} + 128y ^{3}$

factor out two from the expression

$2(27 {x}^{3} + 64 {y}^{3} )$

using ${a}^{3} + {b}^{3} = (a + b)( {a}^{2} - ab + {b}^{2} )$ factor the expression

$2(3x + 4y) \times (9 {x}^{2} - 12xy + 16 {y}^{2} )$
