=====================================

\underline{SOLUTION}SOLUTION ➡

\begin{gathered}(m + n)(m {}^{2} - mn + n {}^{2} ) \\ \\ = m(m {}^{2} - mn + n {}^{2} ) + n(m {}^{2} - mn + n {}^{2} ) \\ \\ = m {}^{3} - m {}^{2} n + mn {}^{2} + m {}^{2} n - mn {}^{2} + n {}^{3} \\ \\ = m {}^{3} - m {}^{2} n + m {}^{2} n - mn {}^{2} + mn {}^{2} + n {}^{3} \\ \\ = m {}^{3} + n {}^{3} \end{gathered}(m+n)(m2−mn+n2)=m(m2−mn+n2)+n(m2−mn+n2)=m3−m2n+mn2+m2n−mn2+n3=m3−m2n+m2n−mn2+mn2+n3=m3+n3

\boxed{(m +n )(m {}^{2} - mn + n {}^{2} ) = m {}^{3} + n {}^{3}}(m+n)(m2−mn+n2)=m3+n3
