Question

(a+b)(a^2-ab+b^2)
please solve this question ​

Answer 1

Answer:

a³+b³

Step-by-step explanation:

(a+b)(a²-ab+b²)=a³+b³

it is reverse form of a³+b³ identity

Answer 2

Step-by-step explanation:

We will discuss here about the expansion of (a ± b)(a2 ∓ ab + b2).

(a + b)(a2 - ab + b2) = a(a2 - ab + b2) + b(a2 - ab + b2)

= a3 - a2b + ab2 + ba2 - ab2 + b3

= a3 + b3.

(a - b)(a2 + ab + b2) = a(a2 + ab + b2) - b(a2 + ab + b2)

= a3 + a2b + ab2 - ba2 - ab2 - b3

= a3 - b3.
