Question

simplify (a+b) (a^2 - ab + b^2) step by step ​

Answer 1

Answer:

= a3+ b3

Step-by-step explanation:

(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

Answer 2

$\underline{\underline{\blue{\textbf{Step - By - Step - Explanation : -}}}}$

›› (a + b)(a² - ab + b²)

›› a(a² + b² - ab) + b(a² - ab + b²)

›› a³ + ab² - a²b + a²b - ab² + b³

›› a³ + b³
