plz step-by-step .......................

Answer 1

Hey !!!

8ab² - 18b³

2a ( 4a² - 9b² )

2a {(2a)² - (3b)² }

now , we know that a² - b² = (a + b) ( a - b )

using this formule

2a( 2a + 3b ) ( 2a - 3b )
$.$

hence, factor of this given polynomial 8ab² - 18a³ is

2a( 2a + 3b ) ( 2a - 2b ) Answer ✔

Answer 2

Hey,

$= 8a {b}^{2} + 18 {a}^{3} \\ = 2a( {4b}^{2} - {9a}^{2} ) \\ = 2a(2b + 3a)(2b - 3a)$

hope it helps u
Thanks
