What are the solutions to the equation? x^3 −8 x^2 −x+8=0

There are 3 solutions I have came up with:

1. x = 1

2.  x = -1

3.  x = 8

4+n=5

step-by-step explanation:

this is because the four is four hours and the n represents the 1 extra hour over the weekend.

b= i'm srry i don't know that one.

4+n=5 n=1 because if vernon plays 5 hours a week then 4+1=5 hours.

hope this : )
