Question

which is the factor of (a³-b³)-(a-b)³
•) a+b
•) a²+b²-ab
•) a²+b²+ab
•) ab​

Answer 1

a³ + b³ = (a + b)(a² – ab + b²)

WHY?

BECAUSE:—

(a + b)³ = a³ + 3ab(a + b) + b³

then a³ + b³ = (a + b)³ – 3ab(a + b)

= (a + b)[(a + b)² – 3ab]

= (a + b)(a² + 2ab + b² – 3ab)

= (a + b)(a² – ab + b² )

I HOPE YOU ARE SATISFIED WITH THE ANSWER

Answer 2

Answer:

a³+b³=( a+b )(a²-ab +b²)

a³-b³= (a-b) (a² +ab +b)
