Answer 1

Answer:

$\huge\red{\boxed{\bold{Answer}}}$

$by \: \\ \\ {a}^{3} - {b}^{3} = (a - b)( {a}^{2} + {b}^{2} + ab) \\ \\ {(2x)}^{3} - ( {3b)}^{3} = (2x - 3b)(4 {x}^{2} + 9 {b}^{2} + 6xb)$

Hope it helps ☺

Answer 2

Answer:

$8 {x}^{3} - 27 {b}^{3}$

$= ( {2x})^{3} - ({3b})^{3}$

$since..{a}^{3} - {b}^{3} = (a - b)( {a}^{2} + {b}^{2} + ab)$

$= (2x - 3b)(4 {x}^{2} + 9 {b}^{2} + 6xb)$
