SOLUTION: The function f(x) = 3x^3 - 2x^2 + x - 2 can be expressed as: a. (x+1) (x^2 + x + 2) b. (x-1) (x^2 + x + 2) c. (x+1) (3x^2 + x + 2) d. (x+1) (3x^2 + x + 2) I think it's C.

Question 391719: The function f(x) = 3x^3 - 2x^2 + x - 2 can be expressed as:
a. (x+1) (x^2 + x + 2)
b. (x-1) (x^2 + x + 2)
c. (x+1) (3x^2 + x + 2)
d. (x+1) (3x^2 + x + 2)
I think it's C. Am I right?

----------
Use limits to describe the end behavior of f(x) = 2 / (divided by) x^2 - 1 at values of x not in its domain.
Thanks for the help.

........ we can write as , and as
...now group them

since you have
c.
d.
which are same, I guess you made mistake by typing d. I think you d should be
d.

Hi,
f(x) = 3x^3 - 2x^2 + x - 2
f(1) = 3 - 2 + 1 - 2 = 0
(x-1) is a factor
f(x)=(x-1) (x^2 + x + 2)
y = 2/(x^2-1) x = 1 and x = -1 excluded from domain
x= -1 and x=1 are the Blues lines on graph below
