(a + b)³- a - b ​

Answer 1

Answer:

(a + b)³- a - b

(a + b)³- (a+b)

(a+b) [(a+b)²-1]

(a+b)(a+b+1)(a+b-1)

hope it helps you...

Answer 2

Step-by-step explanation:

(a + b)³ - (a + b)

=> (a + b) [ (a + b)² - 1² ]

=> (a + b) (a + b + 1)(a + b - 1)

[ x² - y² = (x + y)(x - y) ]

[ here, x = a + b and y = 1 ]
