0 isn't one of them. There are 5 altogether. That comes from 7x^5. The 5 determines how many roots will solve the polynomial.
1 won't work either. Nor will minus 1. Both leave remainders. The only way to get started is to do this by brute force. Go down the list and see who gives a zero.
According to this graph, none of them work. There is one solution and it is marked on the graph. The 1 solution is just larger than -1. Check the question again and if it is different, put a comment at the bottom.

Answer:
x=2 meters
Step-by-step explanation:
length = 12+2x
width = 6+2x
Area = (12+2x) (6+2x) = 160
Foil
72 + 12x+24x+4x^2 = 160
Combine like terms
4x^2 + 36x +72 = 160
Subtract 160 from each side
4x^2 +36x -88 =0
Divide by 4
x^2 +9x -22=0
Factor
What 2 numbers multiply to -22 and add to 9
11 * -2 = -22
11+ -2 = 9
(x +11) (x-2) =0
Using the zero product property
x=-11 x=2
Since we cant have negative length
x=2
80 oz and 5 lbs are the same
Answer:
x = 58
Step-by-step explanation:
The exterior angle is equal to the sum of the opposite interior angles
90 = 32+x
Subtract 32 from each side
90-32 = x
58 =x
