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}
