$\bold\red{SOLUTION:-}$

$\begin{array}{r r r} \end{array} \\ \\ ➤ (x + y) ^{3} - (x^{3} + y ^{3} ) \\ \: \\ using \: \: identity \: = (x^{3} + y^{3} ) = (x + y)(x {}^{2} - xy + y {}^{2} ) \\ \\➤(x + y) {}^{3} - (x + y)(x {}^{2} - xy + y ^{2} ) \\ \\ ➤(x + y) \times \big[(x + y) {}^{2} - (x {}^{2} - xy + y ^{2} ) \big] \\ \\ ➤(x + y) \times (x {}^{2} + 2xy + y {}^{2} - x{}^{2} + xy - y {}^{2} ) \\ \\ ➤(x + y) \times (2xy + xy) \\ \\ ➤(x + y)3xy \\ \\ ⇢ \fbox{3xy(x + y)}$
