Let's factorise it :

$\: {\qquad \dashrightarrow \sf ( {x}^(3) - 5)(x + 3) }$

$\: {\qquad \dashrightarrow \sf {x}^(3) (x + 3) + [-5(x + 3)] }$

Using Distributive property we get :

$\: {\qquad \dashrightarrow \sf {x}^(3) + {3x}^(3) + ( - 5x - 15) }$

$\: {\qquad \dashrightarrow \sf {x}^(3) + {3x}^(3) - 5x - 15 }$

$\: {\qquad \dashrightarrow \sf 4{x}^(3) - 5x - 15 }$

⠀

Therefore,

$\: {\qquad \dashrightarrow \sf ( {x}^(3) - 5)(x + 3) =4{x}^(3) - 5x - 15}$
