Hurry i will fail math if i don't get this no joke

two numbers have a sum of 2 and a product of -8. the quadratic equation -n^2 + 2n + 8= 0 can be used to
determine the two numbers.

a) graph the related function f(n)= -n^8 +2n+8 and determine its x-intercepts

b) what are the two numbers?

for a you can just tell me the x intercepts

for finding the midpoint of any given 2 pair of points simply add the respective x coordinates with other x coordinate and the y coordinate with other y coordinate and divide them by 2

in your question it will be :

(3+1)/2 for the x coordinate of mid point i.e 2

[8+(-4)]/2 for the y coordinate of midpoint i.e 2

so coordinates of mid point of points (3,8) and (1,-4) will be (2,2)

factor trees are nice.
