What are all of the real roots of the following polynomial?
F(x)= x^5 + 5x^4-5x^3 -25x^2+ 4x+20

if im undersanding the question correctly, its organized from 10

step-by-step explanation:

the barter

x = -3

y = -18

step-by-step explanation:

to solve by substitution, substitute one variable and solve for the other. then substitute again to find the remaining variable.

x-1/3(3x-9) = -3 since y=3x-9 substittute y.

x-1/3(3x-9)=-3

x + x +3 = -3

2x+3=-3

2x+3-3= -3-3

2x=-6

x=-3

substitute again into y=3x-9

y=3(-3)-9

y=-9-9

y=-18

answer: median

step-by-step explanation:

the median is the middle value when a data set is ordered from least to greatest
