2\left(a^{3}+2a^{2}b+ab^{2}\right)
Factor out 2.
a\left(a^{2}+2ab+b^{2}\right)
Consider a^{3}+2a^{2}b+ab^{2}. Factor out a.
\left(a+b\right)^{2}
Consider a^{2}+2ab+b^{2}. Use the perfect square formula, p^{2}+2pq+q^{2}=\left(p+q\right)^{2}, where p=a and q=b.
2a\left(a+b\right)^{2}
Rewrite the complete factored expression.
