Question

simplify (a-b) (a^+ab+b^)​

Answer 1

We have:

$(a-b)(a^2+ab+b^2)$

We have to simply the given expression.

Solution:

∴ $(a-b)(a^2+ab+b^2)$

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

= $a^3+a^2b+ab^2-a^2b-ab^2-b^3$

= $a^3+a^2b+ab^2-a^2b-ab^2-b^3$

= $a^3-b^3$

∴ $(a-b)(a^2+ab+b^2)$ = $a^3-b^3$

Thus, the simplication of $(a-b)(a^2+ab+b^2)$ is equal to $a^3-b^3$.
