Question

Hey:) can you please help me posted picture of question

Answer 1

We have the following expression:
(x2 + x + 8) (x - 5)
Rewriting we have:
x3 + x2 + 8x + (-5x2 - 5x - 40)
Adding similar terms:
x3 - 4x2 + 3x - 40
Answer:
The solution for this case is given by:
x3 - 4x2 + 3x - 40

Answer 2

Option A gives the correct answer.

Step by step solution is listed below:


`( x^(2) +x+8)(x-5) \\ \\ =x( x^(2) +x+8)-5( x^(2) +x+8) \\ \\ = x^(3)+ x^(2) +8x-5 x^(2) -5x-40 \\ \\ = x^(3)-4 x^(2) +3x-40`
