The factors of 7are -1 and 7 or 1 and -7, the factors of 14 are 1, 2, 7, and 14, or -1, -2, -7,-14. so the list of potential zeros are: 1/1, 1/2, 1/7, 1/14, 7/1,7/2, 7/7, 7/14, which can be simplified into 1, 1/2,1/7, 1/14, 7, 7/2 add the negative ones: -1, -1/2,-1/7, -1/14, -7, -7/2 I believe there are a total of 12 potential zeros reference: http://www.sparknotes.com/math/algebra2/polynomials/section4.rhtml
To find the Median arrange the data in order from least to greatest then find the middle number. To find the middle number cross of one from the front and one from the bcak. If there are 2 numbers left in the middle add those numbers together and them divided the sum by 2.
The mean is the average of the numbers. It is easy to find. First, add up all the numbers, then divide by how many numbers there are. In other words it is the sum divided by the count.
