Answer:

(2a - 7b ) ( 4a^2 + 14ab + 49b^2 )

Step-by-step explanation:

8a^3 - 343b^3

= (2a)^3 - (7b)^3

= ( 2a - 7b ) [(2a)^2 + 2a x 7b + (7b)^2]

= (2a - 7b) (4a^2 + 14ab + 49b^2 )

HENCE, a^3 - b^3 = (a - b ) ( a^2 + ab + b^2 )

I HOPE IT WILL HELP YOU

And if it helped then please MARK it as the brainliest answer.plz.
