Question 193301: I would just like to know if i calculated the following correctly!
Consider the polynomial f(x) = 3x3 + 13x2 – 11x – 5.
Find all of the zeros of the given polynomial. Be sure to show work, explaining how you have found the zeros.

Highest degree is 3.
Thus, I tried +-1, +-2, +-3
+-1,+-3
All possible zeros are +1 and -1/3
I simply tried it:
1| 3 13 -11 -5
3 16 5
3 16 5 0

-1/3| 3 13 -11 -5
-1 -4 5
3 12 -15 0
all others did not have the remainder 0 but I did it the same way!
