Question

(a+b)(a2-ab+b2)=a3+b3
Why is that equal?

Answer 1

Is that a times 2 or a to the second power?

Answer 2

it wasn't time 2

Answer 3

\[(a + b)(a ^{2} - ab + b ^{2} = a ^{3} + b ^{3}\]

Answer 4

Looks like that?

Answer 5

it was just like that. Is that possible? (a+b)(a2-ab+b2)=a3+b3

Answer 6

Why? Is it asking you if it's true or not?

Answer 7

(a+b)(a2-ab+b2)=a3+b3

Answer 8

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