Question

factorise (a+b)³-3ab(a+b)​

Answer 1

Answer:

a^3 + b^3

Step-by-step explanation:

here,

(a+b)^3 -3ab(a+b)

=a^3 + b^3 + 3ab(a+b) - 3ab(a+b)

=a^3 + b^3

therefore, a^3 + b^3 is the correct answer

Answer 2

Answer:

(a+b)(a²-ab+b²)

Step-by-step explanation:

(a+b)³-3ab(a+b)​

= (a+b){(a+b)² - 3ab}

= (a+b)(a²+b²+2ab-3ab)

= (a+b)(a²-ab+b²)

Ans:-  (a+b)(a²-ab+b²)

2nd process

(a+b)³-3ab(a+b)​

= a³+b³

= (a+b)(a²-ab+b²)

Ans:- (a+b)(a²-ab+b²)
