Question

(a + b)(a^2 - ab + b^2)
im sorry but i need help on this one too

Answer 1

I think that is a sum of cubes

Answer 2

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

Answer 3

Ageta is correct

Answer 4

(a+b)(a2−ab+b2)
=(a+b)(a2+−ab+b2)
=(a)(a2)+(a)(−ab)+(a)(b2)+(b)(a2)+(b)(−ab)+(b)(b2)
=a3−a2b+ab2+a2b−ab2+b3
=a3+b3
