SOLUTION: x^4+5x^3+5x^2-5x-6 This problem has 3 parts part 1 find positive and negative real zeros part 2 find upper and lower bound using synthetic division this is the one that I'm real

Question 466621: x^4+5x^3+5x^2-5x-6
This problem has 3 parts
part 1 find positive and negative real zeros
part 2 find upper and lower bound using synthetic division this is the one that I'm really stuck in I'm not sure witch numbers I need to use here
part 3 finding all possible zeros I haven't gotten to this part because I need to be able to do part 1 & 2 to get to part 3. Can you please explain the whole process. Thank you in advance.

x^4+5x^3+5x^2-5x-6
This problem has 3 parts
part 1 find positive and negative real zeros
x = -1 ; x = -2 ; x = -3 ; x = 1
---------------------------------------------
part 2 find upper and lower bound using synthetic division this is the one that I'm really stuck in I'm not sure witch numbers I need to use here
