SHOW that (x + 3) and (x - 2) are factors of f(x) = x4 + 10x3 + 23x2 -
34x - 120.
1 answer:
If f(x) = 0 then it is a root
x + 3 = 0
x=-3
f(-3) = (-3)^4 + 10(-3)^3 + 23(-3)^2 - 34(-3) - 120 = 0
x - 2 = 0
x=2
f(2) = (2)^4 + 10(2)^3 + 23(2)^2 - 34(2) - 120 = 0

Step-by-step explanation:
Answer:
m = 11/9
Step-by-step explanation:
m = (y2 - y1) / (x2 - x1)
= (-7 - 4) / (-3 - 6)
= -11/-9
= 11/9
