Explanation:
(a+b)³=a³+3ab+3ab²+b³
Step-by-step explanation:
LHS=(a+b)^{3}LHS=(a+b)

=(a+b)(a+b)^{2}(a+b)(a+b)
2
=(a+b)(a^{2}+2ab+b^{2})(a+b)(a

/* By algebraic identity:
\boxed {(x+y)^{2}=x^{2}+2xy+y^{2}}
(x+y)

=x

=a(a^{2}+2ab+b^{2})+b(a^{2}+2ab+b^{2})a(a

= a^{3}+2a^{2}b+ab^{2}+a^{2}b+2ab^{2}+b^{3}a
