Question

CAN SOMEONE MULTIPLY THIS PLEASE, ITS URGENT

Answer 1

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}`
