Question

factorize 8x³- y³/ 343. plz help....thanks​

Answer 1

Step-by-step explanation:

8x³ + 343

8x³ + 343(2x)³ + (7)³

8x³ + 343(2x)³ + (7)³We kow that , (a)³ + (b)³ = ( a + b ) ( a² + b² - ab )

8x³ + 343(2x)³ + (7)³We kow that , (a)³ + (b)³ = ( a + b ) ( a² + b² - ab )( 2x + 7 ) { (2x)² + 7² - 2x*7 }

8x³ + 343(2x)³ + (7)³We kow that , (a)³ + (b)³ = ( a + b ) ( a² + b² - ab )( 2x + 7 ) { (2x)² + 7² - 2x*7 }( 2x + 7 ) ( 4x² + 49 - 14x )

Hence this is required answer .....

HOPE THIS HELPS YOU.......
